Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.

XGC, UHD, RIF, OJI, ?

ALKL
BLKN
CLKM
DLLM

Correct answer: C

Explanation

First letters go back by 3 (X, U, R, O, L). Second letters go forward by 1 (G, H, I, J, K). Third letters change by +1, +2, +3, +4 (C, D, F, I, M). So the next cluster is LKM.
