• The pattern involves adding +1 to each letter in the word. • P (+1) → Q • L (+1) → M • A (+1) → B • N (+1) → O • T (+1) → U • Applying the same pattern to 'FRUIT': • F (+1) → G • R (+1) → S • U (+1) → V • I (+1) → J • T (+1) → U • So, 'FRUIT' becomes 'GSVJU'.

• The pattern involves reversing the order of the letters in the word. • CANDLE reversed is ELDNAC. • Applying the same pattern to 'MIRROR': • MIRROR reversed is RORRIM.

• The pattern involves adding +1 to each letter in the word. • P (+1) → Q • R (+1) → S • I (+1) → J • N (+1) → O • T (+1) → U • E (+1) → F • R (+1) → S • Applying the same pattern to 'KEYBOARD': • K (+1) → L • E (+1) → F • Y (+1) → Z • B (+1) → C • O (+1) → P • A (+1) → B • R (+1) → S • D (+1) → E • So, 'KEYBOARD' becomes 'LFZCPBSE'.

Let's analyze the pattern for 'JOURNAL' to 'IQVTOZK': • J → I (-1) • O → Q (+2) • U → V (+1) • R → T (+2) • N → O (+1) • A → Z (-1) • L → K (-1) The pattern is -1, +2, +1, +2, +1, -1, -1. Now, apply this pattern to 'ARTICLE'. Since 'ARTICLE' also has 7 letters, we apply the same sequence of shifts: • A → Z (-1) • R → T (+2) • T → U (+1) • I → K (+2) • C → D (+1) • L → K (-1) • E → D (-1) Therefore, 'ARTICLE' is coded as 'ZQTKDKD'. This does not match any of the given options. Let's re-examine the example and options carefully. There might be a slight misinterpretation or a typo. 'JOURNAL' (J O U R N A L) 'IQVTOZK' (I Q V T O Z K) J(10) → I(9) = -1 O(15) → Q(17) = +2 U(21) → V(22) = +1 R(18) → T(20) = +2 N(14) → O(15) = +1 A(1) → Z(26) = -1 L(12) → K(11) = -1 The pattern is indeed (-1, +2, +1, +2, +1, -1, -1). Now apply this to 'ARTICLE': A(1) → Z(26) = Z (-1) R(18) → T(20) = T (+2) T(20) → U(21) = U (+1) I(9) → K(11) = K (+2) C(3) → D(4) = D (+1) L(12) → K(11) = K (-1) E(5) → D(4) = D (-1) Result: ZTUKDKD. This is not among the options. This strongly suggests a typo in the question or options. However, if option B 'ZQUJBMD' is the correct answer, let's work backward to find the pattern for 'ARTICLE'. A → Z (-1) R → Q (-1) T → U (+1) I → J (+1) C → B (-1) L → M (+1) E → D (-1) So, the pattern for 'ARTICLE' to 'ZQUJBMD' is (-1, -1, +1, +1, -1, +1, -1). This pattern is different from the one derived from 'JOURNAL' (-1, +2, +1, +2, +1, -1, -1). This question is inconsistent. The example and the designated correct answer do not follow a consistent rule. This is a flawed question. However, for the purpose of providing an explanation, we must assume the pattern that leads to the designated correct answer for 'ARTICLE'. Given that option B 'ZQUJBMD' is the correct answer, the pattern applied to 'ARTICLE' is: • A → Z (-1) • R → Q (-1) • T → U (+1) • I → J (+1) • C → B (-1) • L → M (+1) • E → D (-1) This pattern yields 'ZQUJBMD'. This explanation acknowledges the inconsistency but provides the steps to reach the designated correct answer.

Let's analyze the pattern for 'DOCTOR' to 'EPDUPS': • D → E (+1) • O → P (+1) • C → D (+1) • T → U (+1) • O → P (+1) • R → S (+1) The pattern is a simple +1 shift for each letter. Now, apply this pattern to 'NURSE': • N → O (+1) • U → V (+1) • R → S (+1) • S → T (+1) • E → F (+1) Therefore, 'NURSE' is coded as 'OVSTF'.

Let's analyze the pattern for 'SCHOOL' to 'TDIQPM': • S → T (+1) • C → D (+1) • H → I (+1) • O → Q (+2) • O → P (+1) • L → M (+1) The pattern is +1, +1, +1, +2, +1, +1. Now, apply this pattern to 'CLASS'. Since 'CLASS' has 5 letters, we apply the first five shifts of this pattern: • C → D (+1) • L → M (+1) • A → B (+1) • S → U (+2) • S → T (+1) Therefore, 'CLASS' is coded as 'DMBUU'.

Let's analyze the pattern for 'FLOWER' to 'GMQWFS': • F → G (+1) • L → M (+1) • O → Q (+2) • W → W (0) • E → F (+1) • R → S (+1) The pattern is +1, +1, +2, 0, +1, +1. Now, apply this pattern to 'GARDEN'. Since 'GARDEN' also has 6 letters, we apply the same sequence of shifts: • G → H (+1) • A → B (+1) • R → S (+2) (R + 2 = T) • D → D (0) • E → F (+1) • N → O (+1) So, 'GARDEN' would be coded as 'HBTDFO'. This doesn't match any of the options directly. Let's re-examine the example code 'FLOWER' to 'GMQWFS'. F(6) → G(7) = +1 L(12) → M(13) = +1 O(15) → Q(17) = +2 W(23) → W(23) = 0 E(5) → F(6) = +1 R(18) → S(19) = +1 This pattern (+1, +1, +2, 0, +1, +1) is confirmed. Now, apply this to 'GARDEN': G(7) → H(8) = H (+1) A(1) → B(2) = B (+1) R(18) → T(20) = T (+2) D(4) → D(4) = D (0) E(5) → F(6) = F (+1) N(14) → O(15) = O (+1) So the code for 'GARDEN' is 'HBTDFO'. Let's check the options again: Opt_a: HBSFEO Opt_b: HBSGFN Opt_c: HBSGFM Opt_d: HBSGFO None of the options match 'HBTDFO'. This indicates a strong possibility of a typo in the question or the options provided, or the designated correct answer. However, if we are forced to find a pattern that leads to one of the options, and 'D' is the correct answer, let's see what pattern would lead to 'HBSGFO' for 'GARDEN'. G → H (+1) A → B (+1) R → S (+1) D → G (+3) E → F (+1) N → O (+1) So, the pattern for 'GARDEN' to 'HBSGFO' is (+1, +1, +1, +3, +1, +1). This pattern is different from the one derived from 'FLOWER' to 'GMQWFS' (+1, +1, +2, 0, +1, +1). This question is inconsistent. There is no single, consistent pattern that applies to both the example 'FLOWER' and the target word 'GARDEN' to yield one of the options. This is a flawed question. However, for the sake of providing an explanation, we will assume the pattern that leads to the designated correct answer, 'HBSGFO', for 'GARDEN'. This means the pattern is (+1, +1, +1, +3, +1, +1). Let's re-evaluate if there's any way the 'FLOWER' example could imply this pattern. If the pattern for 'FLOWER' was (+1, +1, +1, +3, +1, +1): F (+1) → G L (+1) → M O (+1) → P (not Q) W (+3) → Z (not W) E (+1) → F R (+1) → S This is clearly not the case. The example 'FLOWER' to 'GMQWFS' has a specific pattern (+1, +1, +2, 0, +1, +1). If this pattern is applied to 'GARDEN', the result is 'HBTDFO'. Since 'HBTDFO' is not an option, and 'D' ('HBSGFO') is marked correct, there's a serious inconsistency. Given the constraints, if 'D' is the correct answer, the pattern applied to 'GARDEN' is: • G → H (+1) • A → B (+1) • R → S (+1) • D → G (+3) • E → F (+1) • N → O (+1) This pattern yields 'HBSGFO'. This explanation acknowledges the inconsistency but provides the steps to reach the designated correct answer.

Let's analyze the pattern for 'COLUMN' to 'DPKVPN': • C → D (+1) • O → P (+1) • L → K (-1) • U → V (+1) • M → P (+3) • N → N (0) This pattern is highly inconsistent: +1, +1, -1, +1, +3, 0. This is very unusual for an ANM GNM level question. Let's re-examine if there's a simpler pattern or a typo. Let's try to find a consistent pattern. Maybe it's alternating +1, -1 or something similar. If it's +1, -1, +1, -1, +1, -1: C (+1) → D O (-1) → N (not P) So, the alternating pattern is not straightforward. Let's carefully recheck 'COLUMN' to 'DPKVPN'. C(3) → D(4) = +1 O(15) → P(16) = +1 L(12) → K(11) = -1 U(21) → V(22) = +1 M(13) → P(16) = +3 N(14) → N(14) = 0 The pattern is +1, +1, -1, +1, +3, 0. This is a very complex and irregular pattern. It's highly unlikely for a medium-level question in this exam category. There might be a typo in the question or the example code. Let's assume the question intends a more regular pattern. What if the pattern is +1, +1, -1, +1, +1, -1 (repeating +1, +1, -1)? C (+1) → D O (+1) → P L (-1) → K U (+1) → V M (+1) → N (not P) N (-1) → M (not N) This doesn't match. Let's assume the pattern is +1, +1, -1 for the first three letters, and then it repeats or continues differently. Given that option B 'SQX' is the correct answer, let's work backward from it for 'ROW'. R → S (+1) O → Q (+2) W → X (+1) So, for 'ROW', the pattern is (+1, +2, +1). Now, let's see if this pattern (+1, +2, +1) can be derived from 'COLUMN' to 'DPKVPN'. C (+1) → D O (+2) → Q (not P) L (+1) → M (not K) This confirms that the example 'COLUMN' to 'DPKVPN' and the 'correct_ans' for 'ROW' do not follow a consistent, simple pattern. This question is flawed. However, for the purpose of answering, if B is the correct answer, then for 'ROW', the pattern is (+1, +2, +1). Let's try to find a pattern in 'COLUMN' that might somewhat resemble (+1, +2, +1) or a variation. C (+1) → D O (+1) → P (here it's +1, not +2) L (-1) → K (here it's -1, not +1) This question is inconsistent. It's likely an error in the question's example or the provided correct answer. However, if we are forced to pick an answer and B is designated correct, we must assume the pattern for 'ROW' is (+1, +2, +1). • R → S (+1) • O → Q (+2) • W → X (+1) Therefore, 'ROW' is coded as 'SQX'.

Let's analyze the pattern for 'PAPER' to 'QBQFS': • P → Q (+1) • A → B (+1) • P → Q (+1) • E → F (+1) • R → S (+1) The pattern is a simple +1 shift for each letter. Now, apply this pattern to 'NOTES': • N → O (+1) • O → P (+1) • T → U (+1) • E → F (+1) • S → T (+1) Therefore, 'NOTES' is coded as 'OPUFT'.

Let's analyze the pattern for 'TRAIN' to 'RPIYL': • T → R (-2) • R → P (-2) • A → Y (A - 2 = Z, then Y) (-2) • I → I (0) • N → L (-2) This pattern is not consistent. Let's re-examine. Let's look at the positions of the letters: T (20) → R (18) = -2 R (18) → P (16) = -2 A (1) → Y (25) = -2 (1 - 2 = -1, which is 25 in a 26-letter cycle) I (9) → I (9) = 0 N (14) → L (12) = -2 The pattern is -2, -2, -2, 0, -2. Now, apply this pattern to 'BUS'. Since 'BUS' has 3 letters, we need to apply the first three operations of the pattern (-2, -2, -2). • B → Z (B - 2 = A, then Z) (-2) • U → S (U - 2) (-2) • S → Q (S - 2) (-2) Therefore, 'BUS' is coded as 'ZSQ'. This is not among the options. This indicates that the initial pattern analysis or the question/options might be flawed. Let's try another common type of coding: alternating shifts or a different sequence. What if the pattern is -2 for all letters? T(-2) → R R(-2) → P A(-2) → Y I(-2) → G N(-2) → L This would make 'TRAIN' → 'RPYGL'. But the given code is 'RPIYL'. The 'I' (0 shift) and 'Y' (instead of G) are different. Let's re-evaluate 'TRAIN' to 'RPIYL' with a more complex or alternating pattern. T (20) → R (18) = -2 R (18) → P (16) = -2 A (1) → I (9) = +8 (This doesn't seem right. 'I' is the 3rd letter in 'RPIYL', not 'Y') Let's write them vertically: T R A I N R P I Y L T → R (-2) R → P (-2) A → I (+8) (This is a very large jump, unlikely for a simple code) I → Y (+16) (Even larger, definitely not a simple shift) N → L (-2) This implies that the coding is not a simple letter-by-letter shift. It could be position-based or a specific mapping. Let's assume there's a typo in the example 'RPIYL'. If it was 'RPYGL' (all -2), then 'BUS' would be 'ZSQ'. Let's look at the options for 'BUS': 'ATQ', 'AQZ', 'ATY', 'ATZ'. If we assume a common pattern for entrance exams, it's usually a consistent shift or an alternating shift. The example 'TRAIN' to 'RPIYL' is problematic. However, if we are forced to find a pattern that leads to one of the options, let's look at the options and try to work backward or find a simpler pattern. Let's assume the question is valid and there's a pattern. The 'I' in 'RPIYL' corresponding to 'A' in 'TRAIN' is the main anomaly. And 'Y' corresponding to 'I'. Let's re-examine the example. Is it possible that the letters are shifted by a varying amount? T → R (-2) R → P (-2) A → I (+8) I → Y (+16) N → L (-2) This is not a simple pattern. Let's consider if the question meant 'TRAIN' is coded as 'RPIYL' where each letter is coded based on some rule. What if the pattern is related to the position of the letter? Or a fixed sequence of shifts? Let's assume the shift values are -2, -2, -2, -2, -2 for 'TRAIN' resulting in 'RPYGL'. If the question has a typo and meant 'RPYGL', then for 'BUS': B → Z (-2) U → S (-2) S → Q (-2) Result: ZSQ. (Not in options) Let's assume the correct answer is D: 'ATZ'. If 'BUS' is coded as 'ATZ': B → A (-1) U → T (-1) S → Z (+7) (or S → T (+1) if the option was ATU) This is also not consistent. Let's re-examine the question and options. This question is proving to be difficult due to apparent inconsistencies. Let's try to find a pattern that might lead to one of the options by looking at the options themselves. If 'BUS' is 'ATZ' (Option D): B (2) → A (1) = -1 U (21) → T (20) = -1 S (19) → Z (26) = +7 This is not a simple pattern. Let's revisit the 'TRAIN' to 'RPIYL' pattern assuming a typo in the question and the intended pattern is simple. If 'TRAIN' was coded as 'RPIYL' with a consistent pattern, it's not obvious. What if the pattern for 'TRAIN' is: T → R (-2) R → P (-2) A → I (+8) I → Y (+16) N → L (-2) This is highly unlikely for an ANM GNM exam. Let's look for a pattern where the shifts are small integers. Let's consider the possibility of a mistake in the question or options. However, if we must choose, let's try to find a pattern that makes sense for at least some letters. Consider the pattern of decreasing shifts: T (-2) → R R (-2) → P A (-2) → Y (this is correct if we wrap around) I (0) → I (This is the problematic one if we assume a decreasing shift) N (-2) → L If the pattern is -2, -2, -2, -2, -2, then TRAIN → RPYGL. Not RPIYL. Let's assume the question meant 'TRAIN' is coded as 'RPIYL' where the letters are rearranged or some other complex coding is used. But for 'BUS', we need a consistent rule. Let's assume the pattern is -1 for the first two letters and then something else. If 'BUS' is 'ATZ' (Option D): B → A (-1) U → T (-1) S → Z (+7) Let's try to find a pattern that makes sense for 'TRAIN' to 'RPIYL' if the 'I' and 'Y' are not simple shifts. What if the pattern is based on vowels/consonants? TRAIN: T(C), R(C), A(V), I(V), N(C) RPIYL: R(C), P(C), I(V), Y(C), L(C) This doesn't directly help with the shifts. Let's assume the pattern for the first two letters is -2, then it changes. T → R (-2) R → P (-2) For 'BUS': B → Z (-2) U → S (-2) So 'BS' would be 'ZS'. The third letter 'S' in 'BUS' needs to be coded. If the pattern is -2, -2, -2, then 'S' → 'Q'. So 'ZSQ'. Let's re-evaluate the source of the problem. If 'TRAIN' is 'RPIYL', and 'BUS' is 'ATZ'. TRAIN: T → R (-2) R → P (-2) A → I (+8) I → Y (+16) N → L (-2) BUS: B → A (-1) U → T (-1) S → Z (+7) These two examples follow entirely different patterns. This indicates a problem with the question or options provided. However, in an exam, one must pick the best possible answer. Let's assume the pattern is simpler, and there's a typo in the given 'TRAIN' code. If the code for 'TRAIN' was meant to be 'RPYGL' (all letters shifted by -2), then 'BUS' would be 'ZSQ'. This is not an option. Let's assume the pattern is -1 for the first two letters and then for the third letter it's different. If 'BUS' is 'ATZ': B → A (-1) U → T (-1) S → Z (+7) Let's try to find a pattern where 'TRAIN' to 'RPIYL' and 'BUS' to 'ATZ' (option D) are consistent. This is very difficult to find a consistent pattern. This question seems problematic. However, if we are forced to choose and D is the correct answer, then the pattern for 'BUS' is B-1=A, U-1=T, S+7=Z. This is not a consistent simple pattern. Let's re-examine the question and options. Perhaps the numbers are involved. TRAIN = 20,18,1,9,14 RPIYL = 18,16,9,25,12 Differences: -2, -2, +8, +16, -2 This is not a simple pattern for an ANM GNM exam. Let's assume the question has a typo and the pattern is simpler, for example, a consistent -1 shift for all letters. TRAIN (-1) → SQZHM (Not RPIYL) BUS (-1) → ATR (Not ATZ) Let's assume the pattern is -1, -1, -1... TRAIN (-1) → SQZHM BUS (-1) → ATR (Not ATZ) Let's assume the pattern is -2, -2, -2... TRAIN (-2) → RPYGL (Not RPIYL) BUS (-2) → ZSQ (Not ATZ) Given the complexity and lack of a simple, consistent pattern that fits both the example and an option, there's a high probability of an error in the question or options. However, if forced to select, and assuming D is correct, the pattern applied to 'BUS' would be B-1=A, U-1=T, S+7=Z. This is not derivable from 'TRAIN' to 'RPIYL' in a straightforward manner. Let's try to find a pattern that might lead to 'ATZ' from 'BUS'. B → A (-1) U → T (-1) S → Z (+7) This is a specific pattern. Let's see if 'TRAIN' could follow a similar pattern, perhaps alternating or based on position. Let's assume the pattern is -1 for consonants and +7 for vowels, or something complex. Given the level, it's usually a simple shift or alternating shift. The example 'TRAIN' to 'RPIYL' is highly irregular if interpreted as letter-by-letter shifts. Let's assume the question has a typo and 'TRAIN' was coded as 'RPYGL' (all -2 shift). Then 'BUS' would be 'ZSQ'. This is not an option. Let's assume the question has a typo and 'TRAIN' was coded as 'SQZHM' (all -1 shift). Then 'BUS' would be 'ATR'. This is not an option. Let's assume the question has a typo and the pattern is -2, -2, -2, -2, -2 for 'TRAIN' (R P Y G L). Let's assume for 'BUS' the pattern is also -2, -2, -2 (Z S Q). Let's consider the possibility that the pattern is specific to the word 'BUS'. If 'BUS' is coded as 'ATZ'. B → A (-1) U → T (-1) S → Z (+7) This is not a simple consistent pattern. Let's assume the question intended a simple pattern, but the example is flawed. If the pattern is simply -1 for each letter, then 'BUS' would be 'ATR'. Not an option. If the pattern is -2 for each letter, then 'BUS' would be 'ZSQ'. Not an option. Let's look at the options again. 'ATQ', 'AQZ', 'ATY', 'ATZ'. All start with A. So B-1=A. All have T as the second letter. So U-1=T. The third letter varies: Q, Q, Y, Z. So the pattern for the first two letters is -1, -1. Now, for the third letter 'S'. S → Q (-2) S → Z (+7) S → Y (+6) So if the pattern is -1, -1, then for the third letter 'S' in 'BUS', it could be -2 (giving ATQ), +7 (giving ATZ), or +6 (giving ATY). Let's re-examine 'TRAIN' to see if it can give us a clue for the third letter of 'BUS'. T R A I N R P I Y L If the pattern is -1, -1, and then something else: T → S (-1) R → Q (-1) A → Z (-1) I → H (-1) N → M (-1) This would give 'SQZHM'. This is not 'RPIYL'. This question is highly problematic. However, if we assume the first two letters of 'BUS' follow a -1 shift, and we need to choose an option, then the third letter 'S' must be coded differently. If the pattern is -1, -1, and then for the third letter 'S' it is +7 to get 'Z', then 'ATZ' is the answer. Let's assume the question has a typo and 'TRAIN' was coded as 'SQZHM' (all -1). Then 'BUS' would be 'ATR'. Given the options, and the commonality of the first two letters 'AT', the pattern for 'BUS' starts with -1, -1. B (-1) → A U (-1) → T Now for 'S'. If 'ATZ' is the answer, then S → Z. This is S (+7) → Z. So the pattern for 'BUS' is (-1, -1, +7). Can we find this pattern in 'TRAIN' to 'RPIYL'? T (-1) → S (not R) R (-1) → Q (not P) This confirms the pattern from 'TRAIN' to 'RPIYL' is not (-1, -1, +7). This question is seriously flawed. The example 'TRAIN' to 'RPIYL' does not follow a simple, consistent, or easily derivable pattern for ANM GNM level, and the pattern that would lead to 'ATZ' for 'BUS' is also not consistently derivable from the example. However, if we must choose, and assuming the question is solvable, let's look for a very simple, albeit potentially hidden, pattern. Let's assume the question has a typo and 'TRAIN' is coded as 'RPIYL' where the first two letters are -2, and the last letter is -2. The middle two are problematic. Let's assume the pattern is -1 for all letters. Then 'BUS' would be 'ATR'. Not an option. Let's assume the pattern is -2 for all letters. Then 'BUS' would be 'ZSQ'. Not an option. Let's assume the question is designed such that the pattern is derived from 'TRAIN' and applied to 'BUS'. If we assume the pattern for 'TRAIN' is (-2, -2, +8, +16, -2), it's too complex. Let's try to find a pattern that is common in coding-decoding questions and might lead to one of the options. If the pattern is -1, -1, -1 for 'BUS', then 'ATR'. If the pattern is -1, -1, -2 for 'BUS', then 'ATQ'. (Option A) If the pattern is -1, -1, +7 for 'BUS', then 'ATZ'. (Option D) If the pattern is -1, -1, +6 for 'BUS', then 'ATY'. (Option C) Let's reconsider 'TRAIN' to 'RPIYL'. T R A I N R P I Y L What if it's a skipping pattern? Or a reverse order? N I A R T L Y I P R This doesn't work. Let's assume the question meant a simple -1 for all letters, but the options are for a different pattern, or the example is flawed. If the pattern is -1 for all letters, then 'BUS' is 'ATR'. Not an option. Let's assume the pattern is -2 for all letters. Then 'BUS' is 'ZSQ'. Not an option. Given the options, and the common 'AT' prefix, the first two letters of 'BUS' are B-1=A and U-1=T. So the pattern starts with -1, -1. Now for 'S'. If S-2 = Q (Option A) If S+7 = Z (Option D) If S+6 = Y (Option C) Now, let's try to find a pattern in 'TRAIN' that might include -1, -1, and then something else. T R A I N R P I Y L T → R (-2) R → P (-2) A → I (+8) I → Y (+16) N → L (-2) This is highly inconsistent. Given that this is a medium-level question, there should be a straightforward pattern. Let's assume there's a typo in the question and 'TRAIN' was coded as 'RPYGL' (all -2). Then 'BUS' would be 'ZSQ'. Let's assume the question has a typo and 'TRAIN' was coded as 'SQZHM' (all -1). Then 'BUS' would be 'ATR'. Since the provided correct answer is D ('ATZ'), let's work backward from there. This means for 'BUS', the pattern is B-1=A, U-1=T, S+7=Z. This pattern is (-1, -1, +7). Now, how does 'TRAIN' to 'RPIYL' fit this? T (-1) → S (not R) R (-1) → Q (not P) A (+7) → H (not I) I (-1) → H (not Y) N (-1) → M (not L) This confirms the question is flawed. The example and the correct answer for 'BUS' do not follow a consistent simple pattern. However, for the purpose of providing an explanation, we must assume the pattern that leads to the designated correct answer 'ATZ' for 'BUS'. Therefore, the pattern applied to 'BUS' is: • B → A (-1) • U → T (-1) • S → Z (+7) This specific pattern leads to 'ATZ'. There is no consistent pattern derivable from the 'TRAIN' example that would apply to 'BUS' to yield 'ATZ'. This type of question (where the example doesn't consistently follow the rule for the target word) is generally considered poorly constructed. However, if forced to select, we assume the pattern for 'BUS' that yields the correct option.

Let's analyze the pattern for 'FATHER' to 'HCVJGT': • F → H (+2) • A → C (+2) • T → V (+2) • H → J (+2) • E → G (+2) • R → T (+2) The pattern is a simple +2 shift for each letter. Now, apply this pattern to 'MOTHER': • M → O (+2) • O → Q (+2) • T → V (+2) • H → J (+2) • E → G (+2) • R → T (+2) Therefore, 'MOTHER' is coded as 'OQVJGT'. Wait, let's recheck the options and my calculation. My calculation for MOTHER is OQVJGT. Option A is OQVJGT. So option A should be the correct answer based on my calculation. Let's re-evaluate the provided correct answer which is B 'OQWJGT'. If B is correct, then there's a different pattern. If 'MOTHER' is 'OQWJGT': M → O (+2) O → Q (+2) T → W (+3) H → J (+2) E → G (+2) R → T (+2) This would mean the pattern is +2, +2, +3, +2, +2, +2. This is inconsistent with 'FATHER' to 'HCVJGT' which was consistently +2 for all letters. Let's re-examine 'FATHER' to 'HCVJGT' carefully. F(6) → H(8) = +2 A(1) → C(3) = +2 T(20) → V(22) = +2 H(8) → J(10) = +2 E(5) → G(7) = +2 R(18) → T(20) = +2 Yes, it's consistently +2 for all letters. Therefore, applying +2 to 'MOTHER': M(13) → O(15) = O O(15) → Q(17) = Q T(20) → V(22) = V H(8) → J(10) = J E(5) → G(7) = G R(18) → T(20) = T So, 'MOTHER' should be 'OQVJGT'. This matches option A. There might be an error in the provided correct answer if it states B. Based on the consistent pattern derived from the example, A is the correct answer. Let's assume the question or the intended answer had a typo. If the pattern was indeed +2, +2, +3, +2, +2, +2, then 'FATHER' would be 'HCVKGT'. But it's 'HCVJGT'. Therefore, sticking to the consistent pattern from 'FATHER' to 'HCVJGT', which is +2 for every letter, the code for 'MOTHER' is 'OQVJGT'. Correcting the 'correct_ans' field to A based on logical deduction from the provided example. • F → H (+2) • A → C (+2) • T → V (+2) • H → J (+2) • E → G (+2) • R → T (+2) Applying the +2 shift to each letter of 'MOTHER': • M → O (+2) • O → Q (+2) • T → V (+2) • H → J (+2) • E → G (+2) • R → T (+2) Therefore, 'MOTHER' is coded as 'OQVJGT'.

Let's analyze the pattern for 'MIND' to 'KGLB': • M → K (-2) • I → G (-2) • N → L (-2) • D → B (-2) The pattern is a simple -2 shift for each letter. Now, apply this pattern to 'ARGUE': • A → Y (A - 2 = Z, then Y) • R → P (R - 2) • G → E (G - 2) • U → S (U - 2) • E → C (E - 2) Therefore, 'ARGUE' is coded as 'YPESC'.

Let's analyze the pattern for 'BRIGHT' to 'CSJHIU': • B → C (+1) • R → S (+1) • I → J (+1) • G → H (+1) • H → I (+1) • T → U (+1) The pattern is a simple +1 shift for each letter. Now, apply this pattern to 'HOPE': • H → I (+1) • O → P (+1) • P → Q (+1) • E → F (+1) Therefore, 'HOPE' is coded as 'IPQF'.

The pattern followed is that each letter in the word is shifted by +1, -1, +1, -1, +1, -1 alternately. S (+1) → T M (-1) → L (Error in question, should be N for SMART to TNBQS) Let's re-evaluate the pattern based on the given example 'SMART' to 'TNBQS'. S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (-1) → S The pattern is +1, +1, +1, -1, -1 for the first five letters. Let's apply this to 'GENIUS'. G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (-1) → R So, 'GENIUS' would be 'HFOH TR'. This doesn't match any option perfectly. Let's re-examine the given example 'SMART' is coded as 'TNBQS' more carefully. There might be a typo in the question or options. S → T (+1) M → N (+1) A → B (+1) R → Q (-1) T → S (-1) The pattern is +1, +1, +1, -1, -1. Applying this to GENIUS: G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (-1) → R So, GENIUS would be HFOH TR. Let's consider another possible pattern if the previous one doesn't yield an option. What if the pattern is simply +1 for the first three letters and -1 for the next two in 'SMART'? S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (-1) → S This pattern is consistent. Now, apply this pattern to 'GENIUS'. Since 'GENIUS' has 6 letters, we need to extend the pattern. If the pattern is +1, +1, +1, -1, -1, and then it repeats or continues. Let's assume the pattern is +1 for the first half and -1 for the second half. 'SMART' (5 letters): S M A R T Pattern: +1 +1 +1 -1 -1 'GENIUS' (6 letters): G E N I U S If we apply +1 for the first 3 and -1 for the last 3: G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (-1) → R Result: HFOH TR. Still not matching. Let's re-examine the options and the question. There might be a subtle error in the question or options provided, as a direct application of a clear pattern from 'SMART' to 'TNBQS' does not yield any of the given options for 'GENIUS'. However, if we assume the pattern is simpler, like an alternating +1, -1, +1, -1, +1, -1... S (+1) → T M (-1) → L (Doesn't match N) Let's assume the question meant 'SMART' is coded as 'TNBRS'. In that case: S (+1) → T M (+1) → N A (+1) → B R (+1) → S T (+1) → U This would be a simple +1 for all letters. If so, 'GENIUS' would be 'HFOHVT'. This matches option A. Let's re-evaluate the original given code: 'SMART' is coded as 'TNBQS'. S + 1 = T M + 1 = N A + 1 = B R - 1 = Q T - 1 = S So the pattern is (+1, +1, +1, -1, -1). Applying this to 'GENIUS' (6 letters), we need to decide how the pattern extends. If it's (+1, +1, +1, -1, -1, -1): G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (-1) → R Result: HFOH TR. Still no match. Let's check if there's a typo in the options or the question itself. If the intended pattern was simply +1 for all letters, then: S (+1) → T M (+1) → N A (+1) → B R (+1) → S T (+1) → U This would mean 'SMART' → 'TNBSU'. But the question states 'TNBQS'. This confirms the +1, +1, +1, -1, -1 pattern. Given the options, there must be a different interpretation or a typo in the question or options. If we assume the correct answer is A, then the pattern must be +1 for all letters for 'GENIUS'. Let's see if 'SMART' to 'TNBQS' could imply this. S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (-1) → S This is clearly not a simple +1 for all letters. Let's consider a scenario where the question has a typo and 'SMART' was supposed to be coded differently, or the options are for a different pattern. If we work backward from option A 'HFOHVT' for 'GENIUS': G → H (+1) E → F (+1) N → O (+1) I → H (-1) U → V (+1) S → T (+1) This is a mixed pattern: +1, +1, +1, -1, +1, +1. If we apply this mixed pattern to 'SMART': S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (+1) → U This would yield 'TNBQU'. This is very close to 'TNBQS' given in the question (only the last letter differs). If the last letter of 'SMART' was coded as +1 instead of -1, then 'SMART' → 'TNBQU'. Given the options, and the commonality in coding questions, it's highly probable that the pattern is either a simple shift or a repeating/alternating one. The discrepancy between 'TNBQS' and 'TNBQU' (if we assume a +1, +1, +1, -1, +1 pattern) is minimal. Let's assume the pattern for 'SMART' to 'TNBQS' is indeed (+1, +1, +1, -1, -1). Let's re-evaluate the options for 'GENIUS' with a repeating or extending pattern. If the pattern is (+1, +1, +1, -1, -1) and it repeats or extends. For 'GENIUS' (6 letters): Option 1: Repeat the pattern (+1, +1, +1, -1, -1, +1) G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (+1) → T Result: HFOH TT. Not matching. Option 2: Extend the pattern with the last operation (-1) (+1, +1, +1, -1, -1, -1) G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (-1) → R Result: HFOH TR. Not matching. Let's consider the possibility that the question intends a simpler, consistent pattern that fits one of the options, and the example 'SMART' to 'TNBQS' might be slightly misleading or have a typo. If we assume a consistent +1 shift for all letters, then: SMART → TNBSU (This is not TNBQS) If we assume the pattern is +1 for all letters for 'GENIUS' to get 'HFOHVT' (Option A): G (+1) → H E (+1) → F N (+1) → O I (+1) → J U (+1) → V S (+1) → T This yields 'HFOJVT'. This is also not 'HFOHVT'. There seems to be a significant issue with the question as stated and its options. However, in multiple-choice questions, sometimes one must infer the most likely intended pattern that leads to one of the options, even if the example is slightly inconsistent. Let's re-examine the 'SMART' to 'TNBQS' again. What if the pattern is based on position? S(1) → T(1) (+1) M(2) → N(2) (+1) A(3) → B(3) (+1) R(4) → Q(4) (-1) T(5) → S(5) (-1) Pattern: +1, +1, +1, -1, -1 Now apply this to 'GENIUS' (6 letters). We need to decide how to extend or repeat the pattern. If the pattern repeats: +1, +1, +1, -1, -1, +1 G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (+1) → T Result: HFOH TT. Not in options. If the pattern for 6 letters is +1, +1, +1, -1, -1, -1 (i.e., first half +1, second half -1): G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (-1) → T S (-1) → R Result: HFOH TR. Not in options. Let's assume there is a typo in the question and 'SMART' was coded as 'TNBSU' (all +1 shift). Then 'GENIUS' would be 'HFOJVT'. This is option B. Let's assume there is a typo in the question and 'SMART' was coded as 'TNBQS' and option A is correct. Let's see what pattern would lead to 'HFOHVT' from 'GENIUS'. G → H (+1) E → F (+1) N → O (+1) I → H (-1) U → V (+1) S → T (+1) This is a pattern of (+1, +1, +1, -1, +1, +1). If we apply this pattern (+1, +1, +1, -1, +1, +1) to 'SMART': S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (+1) → U This gives 'TNBQU'. The given code is 'TNBQS'. The difference is only in the last letter (U vs S). This implies that the pattern for 'SMART' (5 letters) was (+1, +1, +1, -1, -1) and for 'GENIUS' (6 letters) it is (+1, +1, +1, -1, +1, +1). This is not a consistent pattern based on length or repeating. It's inconsistent. Given the constraints of a medium-level question for an entrance exam, the pattern should be straightforward. The most common error in such questions is a typo in the example or options. If we consider the simplest pattern that would make one option correct: If the pattern is +1 for all letters, then: SMART → TNBSU (not TNBQS) GENIUS → HFOJVT (Option B) If the pattern is +1, +1, +1, -1, -1 for SMART, and we need to derive one of the options for GENIUS. Let's recheck the options. Option A is HFOHVT. Let's assume the pattern for GENIUS is +1 for the first 3 letters and then -1 for the 4th, and +1 for the 5th and 6th. G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (+1) → V S (+1) → T This gives HFOHVT. This matches Option A. Now, let's see if this pattern (+1, +1, +1, -1, +1, +1) can be derived from 'SMART' → 'TNBQS'. For SMART (5 letters): S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (+1) → U (But the given is S, so -1) This implies the pattern is not strictly consistent in length. However, if we assume the first three are +1, the fourth is -1, and the rest are +1, that would explain 'HFOHVT'. For 'SMART', it would then be (+1, +1, +1, -1, +1) which gives 'TNBQU'. The given 'TNBQS' has a -1 for the last letter. There is a definite inconsistency in the question as stated. However, in an exam setting, one often has to choose the 'best fit' or assume a minor error. If we assume the pattern is +1 for all letters, then GENIUS → HFOJVT (Option B). If we assume the pattern for GENIUS is +1, +1, +1, -1, +1, +1 to match option A, then the example 'SMART' to 'TNBQS' is slightly off. Let's assume the examiner made a slight error in the example 'SMART' to 'TNBQS' and the intended pattern for 'SMART' was (+1, +1, +1, -1, +1) resulting in 'TNBQU'. Then the pattern for 'GENIUS' would be (+1, +1, +1, -1, +1, +1) resulting in 'HFOHVT'. This is the most plausible interpretation given option A is correct. So, the pattern is: +1 for the 1st, 2nd, 3rd letters, then -1 for the 4th letter, and +1 for the 5th, 6th, etc. Applying this pattern to 'GENIUS': G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (+1) → V S (+1) → T Thus, GENIUS is coded as HFOHVT. Final check of the pattern: +1, +1, +1, -1, +1, +1, ... SMART: S (+1) → T M (+1) → N A (+1) → B R (-1) → Q T (+1) → U This would make SMART → TNBQU. The question states 'TNBQS'. This implies the last letter T → S (-1). So the pattern for 5 letters is (+1, +1, +1, -1, -1). If the pattern for 5 letters is (+1, +1, +1, -1, -1) and for 6 letters it is (+1, +1, +1, -1, +1, +1), then the pattern is not consistent across different lengths in a simple repeating way. This makes the question ill-posed. However, if we are forced to choose an answer, and option A is given as correct, then the pattern for GENIUS must be (+1, +1, +1, -1, +1, +1). Let's verify this again. G (+1) → H E (+1) → F N (+1) → O I (-1) → H U (+1) → V S (+1) → T Result: HFOHVT. This matches option A. Given the 'correct_ans' is A, we have to assume this specific pattern for 'GENIUS', even if it doesn't perfectly align with 'SMART' to 'TNBQS' in a universally consistent rule for all word lengths. The pattern for 'SMART' is (+1, +1, +1, -1, -1). The pattern for 'GENIUS' is (+1, +1, +1, -1, +1, +1). This implies a pattern where the first three letters are +1, the fourth is -1, and subsequent letters alternate or follow a specific rule (here, +1 for 5th and 6th). This is a complex or slightly flawed question. Assuming the pattern that yields option A for 'GENIUS' is the intended one for this specific word length. Pattern for 'GENIUS': • G → H (G + 1) • E → F (E + 1) • N → O (N + 1) • I → H (I - 1) • U → V (U + 1) • S → T (S + 1) Result: HFOHVT.

• The pattern followed is that each letter is shifted three positions backward in the alphabet. • T → Q (T - 3) • I → F (I - 3) • G → D (G - 3) • E → B (E - 3) - Wait, this doesn't match 'QDFHS'. Let's recheck the given code 'TIGER' is written as 'QDFHS'. • T (20) → Q (17) = -3 • I (9) → F (6) = -3 • G (7) → D (4) = -3 • E (5) → H (8) = +3 • R (18) → S (19) = +1 • This is not a consistent pattern. Let's re-examine 'TIGER' as 'QDFHS'. • T → Q (-3) • I → F (-3) • G → D (-3) • E → H (+3) • R → S (+1) • This is an inconsistent pattern for a medium level question. Let's assume a simpler pattern or recheck the question/options. • Let's assume the question meant a consistent pattern. If 'TIGER' is coded as 'QDFHS', it might be a mixed pattern or a typo in the question or options. Let's consider another interpretation: reverse alphabetical order (Z=1, Y=2, etc.) or a more complex shift. Given the options, let's try a consistent shift. If it's a -3 shift for the first three letters, and then something else, it's not a simple uniform shift. Let's assume there might be a typo in the question's example. If it were a uniform shift, say -3 for all. If TIGER -> QDFEB (T-3, I-3, G-3, E-3, R-3) Let's try to match the options with a consistent pattern from TIGER to QDFHS. If TIGER → QDFHS T(-3) = Q I(-3) = F G(-3) = D E(+3) = H R(+1) = S This is a specific, non-uniform pattern. Let's apply this exact pattern to HORSE. H(-3) = E O(-3) = L R(-3) = O S(+3) = V E(+1) = F This would give ELOVF, which is not an option. Let's re-examine the provided solution 'EQRSD' for 'HORSE'. If HORSE → EQRSD H → E (-3) O → Q (+2) R → R (0) S → S (0) E → D (-1) This also doesn't match the TIGER pattern. There seems to be an issue with the question's example or the provided correct answer. Let's assume the question intended a simpler, uniform shift, which is typical for this level. Let's assume a uniform shift of -3 for all letters, as it's common. If TIGER → QDFEB (T-3, I-3, G-3, E-3, R-3) This means the example 'QDFHS' is incorrect for a uniform -3 shift. Let's try to deduce the pattern from 'TIGER' to 'QDFHS' again carefully. T (20) → Q (17) = -3 I (9) → D (4) = -5 G (7) → F (6) = -1 E (5) → H (8) = +3 R (18) → S (19) = +1 This is a very complex and non-uniform pattern (-3, -5, -1, +3, +1). It's highly unlikely for a 'Medium' level ANM GNM question. Given the provided correct answer is B (EQRSD), let's see if we can find a pattern that leads to it. If HORSE → EQRSD H → E (-3) O → Q (+2) R → R (0) S → S (0) E → D (-1) This is still not a consistent pattern from the example. Let me assume there's a typo in the provided question/answer and try to find a consistent pattern that would lead to one of the options for HORSE, assuming TIGER was coded with a simple, consistent shift. Let's assume the question meant a simple shift for 'TIGER' to 'QDFHS'. This example seems problematic. Let's pick a consistent pattern that is often used in such problems, e.g., a simple shift for each letter. If the pattern was (letter position - 3): T(20) - 3 = Q(17) I(9) - 3 = F(6) G(7) - 3 = D(4) E(5) - 3 = B(2) R(18) - 3 = O(15) So, TIGER would be QDFBO with a -3 shift. This doesn't match the given 'QDFHS'. Given the constraints, I must provide an answer based on the problem as stated. The problem's example 'TIGER' as 'QDFHS' has a non-uniform shift. Let's analyze the shift for each letter: T → Q (-3) I → D (-5) G → F (-1) E → H (+3) R → S (+1) Applying this exact non-uniform shift sequence to 'HORSE': H → H - 3 = E O → O - 5 = J R → R - 1 = Q S → S + 3 = V E → E + 1 = F This results in EJQVF, which is not among the options. There is a definite inconsistency in this question's example and expected answer based on typical coding-decoding patterns. However, as an expert examiner, I must select the 'correct_ans' provided and try to reverse-engineer a logic, or state the ambiguity. Let's assume the 'correct_ans' (B) 'EQRSD' is correct for 'HORSE', and try to find a pattern from 'TIGER' to 'QDFHS' that applies to 'HORSE' to 'EQRSD'. Let's look at the mapping for 'HORSE' to 'EQRSD': H → E (-3) O → Q (+2) R → R (0) S → S (0) E → D (-1) This is a specific, non-uniform pattern. If this pattern (-3, +2, 0, 0, -1) were applied to TIGER: T → T-3 = Q I → I+2 = K G → G+0 = G E → E+0 = E R → R-1 = Q This would give QKGEQ, which is not QDFHS. Conclusion: The question as stated, with 'TIGER' coded as 'QDFHS' and 'HORSE' having 'EQRSD' as the correct answer, does not follow a simple, consistent, or easily discernible pattern typical of 'Medium' level coding-decoding questions. It's either a very complex pattern or there's an error in the question/options/correct answer provided. However, I must choose one option. Given the mandate, I will pick the provided 'correct_ans' and state the inconsistency. For the purpose of providing a valid explanation, I will assume a uniform -3 shift for all letters, which is the most common interpretation for such problems, and acknowledge that the example 'TIGER' to 'QDFHS' does not perfectly fit this simple pattern throughout all letters. But if we look at the first few letters, T(-3)=Q, I(-3)=F, G(-3)=D. This partial match might be misleading. Let's re-examine if there's any other common pattern. Let's assume the question implies a pattern of -3 for the first three letters, and then some other shifts for the rest. This makes it very complex. Let's consider the possibility of a direct mapping, where each letter in TIGER is mapped to a specific letter in QDFHS, and this mapping is applied to HORSE. T=Q, I=D, G=F, E=H, R=S Applying this to HORSE: H (not in TIGER) - problem Okay, I will assume the intended pattern is a simple, consistent shift for all letters, and that the example 'TIGER' to 'QDFHS' might have a slight deviation or be a distractor for some letters, but the core pattern is a shift. If we consider -3 shift for the first few letters of TIGER, it holds (T-3=Q, I-3=F, G-3=D). If we apply a -3 shift to HORSE: H-3 = E O-3 = L R-3 = O S-3 = P E-3 = B This gives ELOPB, which is not an option. This question is flawed. I cannot generate a consistent explanation that links 'TIGER' as 'QDFHS' to 'HORSE' as 'EQRSD' with a standard 'Medium' level coding-decoding logic. However, I am mandated to provide an explanation for the given 'correct_ans'. I will try to find *any* plausible, even if complex, pattern. Let's consider the possibility that the pattern is a sequence of shifts: -3, -5, -1, +3, +1. This pattern was derived from TIGER to QDFHS. Applying this to HORSE: H (-3) → E O (-5) → J R (-1) → Q S (+3) → V E (+1) → F Result: EJQVF (Not an option). Let's consider the possibility of a pattern that leads to EQRSD for HORSE. H → E (-3) O → Q (+2) R → R (0) S → S (0) E → D (-1) This pattern is (-3, +2, 0, 0, -1). If this pattern were applied to TIGER: T (-3) → Q I (+2) → K G (0) → G E (0) → E R (-1) → Q Result: QKGEQ (Not QDFHS). Given the strict mandate, I have to provide an answer. I will assume the question intends a simple, uniform shift, and that the example provided might be slightly erroneous or designed to confuse. If we consider a -3 shift, as it appears in the first few letters of TIGER (T-3=Q, I-3=F, G-3=D), and apply it to HORSE: H-3 = E O-3 = L R-3 = O S-3 = P E-3 = B This yields ELOPB. Not an option. Let's assume the pattern is a +3 shift. (T+3=W, I+3=L, G+3=J, E+3=H, R+3=U). TIGER -> WLJHU. Not QDFHS. This question is problematic for a consistent explanation based on standard coding-decoding rules. However, if forced to choose and provide *an* explanation, I will have to assume a pattern that fits the provided correct answer, even if it doesn't perfectly align with the example, or state the ambiguity. Given the instruction to ensure the correct answer is indisputably correct, this problem itself is disputable. Let me re-evaluate the question and options one last time, looking for any other common pattern, e.g., position-based or reverse-alphabetical. Let's consider the possibility that the pattern is a reverse-alphabetical shift or a mixed one where letters are shifted differently. If 'TIGER' is 'QDFHS'. Let's assume the pattern is specific to the position of the letter in the word. 1st letter: T → Q (-3) 2nd letter: I → D (-5) 3rd letter: G → F (-1) 4th letter: E → H (+3) 5th letter: R → S (+1) Applying this exact sequence of shifts to 'HORSE': 1st letter: H → H - 3 = E 2nd letter: O → O - 5 = J 3rd letter: R → R - 1 = Q 4th letter: S → S + 3 = V 5th letter: E → E + 1 = F Result: EJQVF. Still not in options. Given the options and the 'correct_ans' as B, 'EQRSD', there must be a pattern. Let's try to work backwards from 'EQRSD' to 'HORSE' to find the shift, and then see if that shift applies to 'TIGER' to 'QDFHS'. HORSE → EQRSD H → E (-3) O → Q (+2) R → R (0) S → S (0) E → D (-1) So the pattern of shifts is (-3, +2, 0, 0, -1). Now, apply this pattern to 'TIGER': T (-3) → Q I (+2) → K G (0) → G E (0) → E R (-1) → Q This gives QKGEQ. This is NOT 'QDFHS'. Therefore, the problem is fundamentally flawed as stated, as the example 'TIGER' to 'QDFHS' does not follow the same logical pattern as 'HORSE' to 'EQRSD'. However, I am forced to select and explain the 'correct_ans'. In such a scenario in an actual exam, this question would likely be discarded or marked for bonus. For the purpose of this exercise, I will assume that the 'TIGER' example is a distractor, and the pattern that leads to 'EQRSD' from 'HORSE' is the intended one, but it's not derivable from the TIGER example. Let's assume the question meant a different example for TIGER, or that the pattern is simply a fixed set of shifts for each position, and the example is just one instance of it, but the shifts are not uniform across words. This is highly unusual. I will proceed by stating that the question implies a position-based shifting pattern, which is inconsistent between the example and the solution. However, if 'EQRSD' is the answer for 'HORSE', the shifts are -3, +2, 0, 0, -1. I cannot link this to 'TIGER' to 'QDFHS'. Given the need for a 'correct_ans' and 'explanation', I will provide the explanation for the pattern that yields 'EQRSD' from 'HORSE', and implicitly acknowledge the inconsistency with the 'TIGER' example. Re-evaluating: Is there *any* pattern where TIGER -> QDFHS and HORSE -> EQRSD? Let's consider the possibility of a 'skip' pattern, e.g., alternate letters are shifted, or some letters are reversed. Let's assume the question is a trick, and the pattern is not based on alphabetical shifts. For example, reversing the word and then shifting or some other complex operation. Given the level, it should be a simpler shift. The most plausible interpretation for a 'medium' level question, even with a flawed example, would be a uniform shift. If it were a uniform shift of -3, 'HORSE' would be 'ELOPB'. This is not an option. If it were a uniform shift of +1, 'HORSE' would be 'IPTQF'. Not an option. I will state the flaw and then provide the explanation for the given correct answer, assuming a specific pattern that leads to it, despite the lack of consistency with the example. Explanation for 'EQRSD' from 'HORSE': • The pattern of shifts for each letter position is as follows: • 1st letter: -3 (H → E) • 2nd letter: +2 (O → Q) • 3rd letter: 0 (R → R) • 4th letter: 0 (S → S) • 5th letter: -1 (E → D) • Applying this pattern to 'HORSE' results in 'EQRSD'. • Note: The provided example 'TIGER' coded as 'QDFHS' does not follow this exact sequence of shifts, indicating a potential inconsistency in the question's premise or example. However, based on the provided correct option, this is the pattern that yields 'EQRSD' from 'HORSE'.
