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

NMRQ, NDZG, NUHW, NLPM, ?

NCXC

Explanation:

NMRQ, NDZG, NUHW, NLPM, ?

The logic followed here is :

N → (0) → N → (0) → N → (0) → N → (0) → N

M → (-9) → D → (-9) → U → (-9) → L → (-9) → C

R → (+8) → Z → (+8) → H → (+8) → P → (+8) → X

Q → (-10) → G → (-10) → W → (-10) → M → (-10) → C

So, the letter-cluster that replaces the (?) to complete the series is "NCXC"
