please select the best answer from the choices provided

○ a
○ b
○ c

Explanation:

Acid rain forms when acidic pollutants (e.g., sulfur dioxide, nitrogen oxides) from air pollution react with water in the atmosphere. Water pollution affects water bodies directly, climate change refers to long-term weather shifts, and ultraviolet rays are related to ozone depletion—none of these cause acid rain directly.

A. air pollution
