Select the letter-cluster that can replace the question mark (?) in the following series.
AYD, BVF CSH, ?

Given: AYD, BVF CSH, ?

Logic: (First letter increases by +1), (Second letter decreases by -3), ( Third letter increases by +2)

First letter: A → B → C → D (Alphabet increases by 1)

Second letter: Y → V → S → P (Alphabet decreases by 3)

Third letter: D → F → H → J (Alphabet increases by 2)

Thus, the missing term is DPJ.

Thus, the Correct Answer: (c) DPJ.
