A.

C.

YDJ 81

D.

YYV 81

Correct option is A

Information Given:
Series:
STQ 54 → NOL 61 → IJG 68 → DEB 75 → ?

Logic:
Each letter decreases by 5 positions; number increases by 7.

S → N → I → D → Y = −5
T → O → J → E → Z = −5
Q → L → G → B → W = −5

54 → 61 → 68 → 75 → 82 = +7

So, next term = YZW 82
