Correct answer: C
Concept
An element in a letter series qualifies only when all stated neighbour conditions hold at the same position.
To count such vowels, inspect each vowel as the centre of a three-letter window: the left neighbour must be a vowel and the right neighbour must be a consonant. A boundary letter without both neighbours cannot qualify.
Application
List the vowels in the series: A at the first position, E at the third position, A at the thirteenth position, and E at the fourteenth position.
The first A has no left neighbour, so it cannot satisfy both neighbour conditions.
For E at the third position, the left neighbour is B, a consonant.
For A at the thirteenth position, the left neighbour is S, a consonant.
For E at the fourteenth position, the left neighbour is A, a vowel, and the right neighbour is H, a consonant. This position satisfies both conditions.
Cross-check
Reading every vowel-centred triple gives B–E–R, S–A–E, and A–E–H; only A–E–H has a vowel on the left and a consonant on the right. The initial A is excluded because it lacks a left neighbour.
Result
Exactly 1 vowel meets both conditions.
