Answer and explanation

Correct answer: {5, 9}

A set B is a subset of A when every element of B is also an element of A. In option A, both 5 and 9 belong to A = {5, 7, 9}, so {5, 9} is a subset of A. Option B contains 8, option C contains 10, and option D contains 4; none of these numbers belongs to A. Thus option A is the only correct answer.
