Which option gives a two-element subset of A = {2, 4, 6}?
Answer and explanation
Correct answer: {2, 4}
A subset must contain only elements that belong to the original set A. A two-element subset must also contain exactly two distinct elements. The set {2, 4} satisfies both conditions because 2 and 4 are in A and there are exactly two elements. Option B contains 8, which is not in A; option C has three elements; and option D has only one element.
