Answer and explanation

Correct answer: A ≠ B

Two sets are equal only when every element of one set is also an element of the other set, with no extra element in either set. Here, 7 belongs to B but does not belong to A. Therefore, the sets do not contain exactly the same elements, so A ≠ B. Both sets are finite, not empty or infinite.
