A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.

QRM, PWD, OBU, NGL, ?

MLC

--> Each letter in the original word is shifted one position to the left. Let's apply this pattern to each term:

1) QRM (Q -> P, R -> Q, M -> L)

2) PWD (P -> O, W -> V, D -> C)

3) OBU (O -> N, B -> A, U -> T)

4) NGL (N -> M, G -> F, L -> K)

Applying the same pattern to the next term:

5) MCL (M -> L, C -> B, L -> K)
