Which option correctly describes A={a,b,c}?
Answer and explanation
Correct answer: A is the set of the first three letters of the English alphabet
The description of a set must produce exactly the listed members. The first three English alphabet letters are a, b, and c, so that description matches A={a,b,c} exactly and option A is correct. The last three letters are x, y, and z. The vowels and consonants are larger, different collections, so options B, C, and D cannot describe A.
