Answer and explanation
Correct answer: B = {a, e, i, o, u}
In the usual elementary classification of the English alphabet, the vowels are a, e, i, o, and u. The letters b, c, and d are consonants, so option B is incorrect. The letter y is not included in the standard vowel list used in this question. Hence the complete roster form is option A.
