Answer and explanation

Correct answer: {1, 2, 3}

The natural-number factors of 12 are A = {1, 2, 3, 4, 6, 12}. The intersection A ∩ B contains only elements common to this factor set and B = {1, 2, 3, 5}. The common elements are 1, 2, and 3; 5 is not a factor of 12, while 4, 6, and 12 are not in B. Hence, A ∩ B = {1, 2, 3}.
