Answer and explanation

Correct answer: P = Q

The positive odd numbers less than 8 are obtained by checking 1, 2, 3, 4, 5, 6, and 7: they are 1, 3, 5, and 7. Thus Q = {1, 3, 5, 7}, which is exactly the set P. Since sets are equal when they contain the same elements, P = Q. Q is finite, not infinite.
