DBZ : WUS :: PNL : ?
Answer & explanation
Correct answer: option 1

Explanation:
DBZ : WUS :: PNL : ?
The logic followed here is :
D → (-7) → W → (-7) → P → (-7) → I
B → (-7) → U → (-7) → N → (-7) → G
Z → (-7) → S → (-7) → L → (-7) → E
So, the letter-cluster that replaces the (?) to complete the series is "IGE"
