A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
MQRT, JNOQ, GKLN, DHIK, ?

Correct option is C

First letters: M, J, G, D → Each letter decreases by 3:
M (13) → J (10) → G (7) → D (4)
Next: D - 3 = A.
Second letters: Q, N, K, H → Each letter decreases by 3:
Q (17) → N (14) → K (11) → H (8)
Next: H - 3 = E.
Third letters: R, O, L, I → Each letter decreases by 3:
R (18) → O (15) → L (12) → I (9)
Next: I - 3 = F.
Fourth letters: T, Q, N, K → Each letter decreases by 3:
T (20) → Q (17) → N (14) → K (11)
Next: K - 3 = H.
Thus, the missing term is AEFH,
Correct answer is (c) AEFH.
