Answer and explanation

Correct answer: A = B

The positive even integers less than 10 are 2, 4, 6, and 8. Hence the set-builder description gives B = {2, 4, 6, 8}. Since this is exactly the roster form of A, both sets contain the same elements and A = B. No other positive even integer below 10 exists.
