Answer and explanation
Correct answer: {2,3}
A set X is a subset of A when every element of X is also an element of A. Here A contains 1, 2, and 3. Both elements of {2,3} occur in A, so {2,3}⊆A. The other choices contain 4, which is not in A; in particular, C={2,3,4} is not a subset of A because of the element 4.
