Refer to the following letter and symbol series and answer the question that follows. Counting to be done from left to right only.
(Left) G C & R Q Y # E S * £ B U C & % D @ U $ P % Q & E (Right) How many such symbols are there each of which is immediately preceded by a vowel but not immediately followed by a vowel?

Correct option is B

We need to count symbols that have a vowel immediately before them, but no vowel immediately after. Go left to right and track each symbol. Only one such valid case appears in the sequence: U $ P, where $ is preceded by vowel U and not followed by a vowel. Hence, answer is one.
Explanation of options: (a) ✘ Overcounts unrelated symbols or ignores the vowel-following condition. (b) ✔ Correct — only $ satisfies the exact condition of being after a vowel and not before a vowel. (c) ✘ There is at least one valid case (U $ P), so this is incorrect. (d) ✘ Two would imply one more case like $, but none exist in the sequence.
