Answer and explanation

Correct answer: {4, 7}

For a set B to be a subset of A, every element of B must belong to A. In option A, {4, 7} contains 7, but 7 is not in A = {4, 5, 6}; hence it is not a subset. The set {4} and the set {5, 6} contain only elements of A. The empty set is also a subset of every set, so option A is the unique answer.
