Answer and explanation

Correct answer: A = {p, q} and B = {q, p}

Set equality depends on the elements present, not on the order in which they are written. Both sets in option B contain exactly p and q, so they are equal. In option A, 3 and 4 differ; in option C, {0} has one element while ∅ has none; and in option D, B has the additional element 6.
