Answer and explanation

Correct answer: {1, 3}

A set X is a subset of A when every element of X is also an element of A. The empty set, {1}, and {2} all satisfy this condition. However, {1, 3} contains 3, and 3 is not an element of A = {1, 2}. Therefore {1, 3} is not a subset, making option D correct.
