Correct Answer: D
Explanation:
If counselor A is not chosen, then counselors B and C will be chosen as there must be at least two counselors on the hike. If counselor C is chosen, camper M can not be chosen, leaving the maximum number of girls possible on the hike at two. Therefore, since boys may not outnumber girls, D cannot be chosen as choosing D would mean also selecting E and F, thus outnumbering the girls.
