Which set is not a subset of A = {1, 2, 3, 4}?
Answer and explanation
Correct answer: {3, 5}
For a set to be a subset of A, each of its elements must belong to A = {1, 2, 3, 4}. Options A, B, and C contain only elements from A, so they are subsets. Option D contains 3, which is in A, but also contains 5, which is not in A. A single element outside A is enough to disqualify the set as a subset. Therefore, option D is correct.
