Correct answer: B

Concept

A vowel qualifies only when both of its immediate neighbours exist: the letter on its left must be a consonant, and the letter on its right must be a vowel.

Thus, inspect each vowel from left to right and count it only if the local three-letter pattern is consonant–vowel–vowel.

Application

  1. List the vowels in the series: E, E, A, I and O.

  2. The first E is in B–E–V; its right neighbour V is a consonant, so it does not meet both conditions.

  3. The second E is in Q–E–A; Q is a consonant and A is a vowel, so this E meets both conditions.

  4. A is in E–A–H; its left neighbour E is a vowel, so it does not meet both conditions.

  5. I is in C–I–V; its right neighbour V is a consonant, so it does not meet both conditions.

  6. O is the final letter and has no right neighbour, so it cannot meet both conditions.

Cross-check

Scanning all adjacent triples yields only Q–E–A in the required consonant–vowel–vowel form. Therefore, the count is one.
