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

ABNC, HGWN, OLFY, VQOJ, ?

CVXU

Explanation:

ABNC, HGWN, OLFY, VQOJ, ?

The logic followed here is :

A → (+7) → H → (+7) → O → (+7) → V → (+7) → C

B → (+5) → G → (+5) → L → (+5) → Q → (+5) → V

N → (+9) → W → (+9) → F → (+9) → O → (+9) → X

C → (+11) → N → (+11) → Y → (+11) → J → (+11) → U

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