A (13, 15)
B (13, 19)
C (13, 17)
D (15, 17)
Correct Answer & Explanation
Option C
Each pair consists of two consecutive prime numbers (pₙ, pₙ₊₁): First pair: (2, 3) Second pair: (3, 5) Third pair: (5, 7) Fourth pair: (7, 11) Fifth pair: (11, 13) • Following consecutive primes after 11 are 13 and 17, so the next pair is (13, 17).
