Prep Test 7 - Section 1- Question 15

I got this answer wrong and was unsure of my answer. Is the correct AC A right because it strengthens the premises to fill in a gap where the deer population increase after the hunting ban could still exist even without the hunting ban? Like for example, a change in the ecosystem in which a predator of deer migrates etc.

I choose B because the key words relating to accidents and public saftey. I felt skeptical about this choice because the AC was reiterating what was already in the stimulus

Can anyone offer any advice on how to more easily eliminate B and choose A when answering this question?
