Correct Answer & Explanation
Option B
The pattern is +1 for the first letter, -1 for the second, +1 for the third, and so on.
L (+1) = M
I (-1) = H
G (+1) = H
H (-1) = G
T (+1) = U
Following this pattern for 'HEAVY':
H (+1) = I
E (-1) = D
A (+1) = B
V (-1) = U
Y (+1) = Z
Therefore, 'HEAVY' is coded as 'IDBUZ'.
