This question is based on the following letter groups.
IOP NUO VEO AIP
In each letter-cluster, each vowel is replaced by the letter immediately following it in the English alphabetical series and each consonant is replaced by the letter immediately preceding it in the English alphabetical series. In how many letter groups formed in this way will no vowels be seen?

One
Why this answer is correct
The logic follows here is :-
Given letter groups: IOP, NUO, VEO, AIP
Operation rules:
- Vowels (A, E, I, O, U) are replaced by the immediately following letter.
- Consonants are replaced by the immediately preceding letter.
Applying the operations to each group:
IOP: I (vowel) → J; O (vowel) → P; P (consonant) → O.
New group: JPO (Contains vowel 'O')
NUO: N (consonant) → M; U (vowel) → V; O (vowel) → P.
New group: MVP (No vowels)
VEO: V (consonant) → U; E (vowel) → F; O (vowel) → P.
New group: UFP (Contains vowel 'U')
AIP: A (vowel) → B; I (vowel) → J; P (consonant) → O.
New group: BJO (Contains vowel 'O')
Analyzing the newly formed groups: JPO, MVP, UFP, BJO.
Only one group (MVP) contains no vowels.
Thus, the correct answer is "Option 2".
