Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. IFQE.
The series follows this pattern:
M - 2 = K, K - 2 = I; I - 2 = G; G - 2 = E
D + 1 = E, E + 1 = F; F + 1 = G; G + 1 = H
S - 1 = R, R - 1 = Q; Q - 1 = P; P - 1 = O
A + 2 = C, C + 2 = E; E + 2 = G; G + 2 = I
