Correct answer: D
Concept
A letter satisfies a neighbour condition only when both of its immediate neighbours match the specified categories. First identify the vowels A, E, I, O and U, then inspect the letter directly before and after each candidate; an endpoint cannot satisfy a condition that requires two neighbours.
Application
The candidate E is between W and S, so its left neighbour W is a consonant.
The candidate I is between S and C, so its left neighbour S is a consonant.
The candidate O is between Z and R, so its left neighbour Z is a consonant.
The candidate A is between H and K, so its left neighbour H is a consonant.
The candidate U is at the right endpoint; it has no following letter, and its left neighbour K is a consonant.
Cross-check
An independent scan of the three-letter windows centred on vowels gives W-E-S, S-I-C, Z-O-R and H-A-K; each begins with a consonant. U is an endpoint. Therefore no vowel forms the required vowel–vowel–consonant pattern.
The required count is 0.
