Let A = {a, e, i, o, u} and B = {i, o}. Which of the following statements is true?
- A is a subset of B
- B is a subset of A
- A equals B
- A is equivalent to B
Correct answer: B is a subset of A
Solution
Every element of B (namely i and o) is also an element of A, so B is a proper subset of A; the reverse does not hold since A has elements not in B.
