PLEASE HELP ASAP Which of the following would provide the best evidence to support the claim that acid rain has a long-term effect on the stability of ecosystems?

Extinction of aquatic and terrestrial organisms would occur, decreasing species diversity and ecosystem stability.
The mutation rate would increase and new species would evolve, destabilizing ecosystems.
The pH level would increase and become intolerable to organisms, leading to decreased species diversity and ecosystem stability.
Habitat loss would occur, forcing organisms to adapt to new surroundings until the ecosystem eventually stabilized.
