I gave my students this multiple choice question: How does acid rain most likely affect forests?

Only one answer is correct among these 4 choices:
- Top soil loses all of its nutrients.
- Plants begin to grow deeper roots.
- Animals have more food sources.
- Trees become less healthy over time.

Could you tell me which one is correct?

Trees become less healthy over time.
