RRB NTPC 2025 Graduate CBT 2 Question Paper PDF (10-Jul-2026) (Shift 1)
The correct answer is

PNP

Read the first letters of each triplet: L, M, N, O … so the next block begins with P.

The middle letters run J, K, L, M … so the next middle letter is N.

The third letters run L, M, N, O … so the next third letter is P.

Hence, the missing triplet is PNP.
