Which is the roster form of I = {x : x is a vowel of the English alphabet}?
Answer and explanation
Correct answer: I = {a, e, i, o, u}
The set is defined as the set of vowels in the English alphabet. In the standard school convention, the vowels are a, e, i, o and u. A roster form lists every member explicitly inside braces, so I = {a, e, i, o, u}. The letter y is not included in this convention, and omitting u would make the list incomplete.
