Answer

A

Explanation

Acid rain disrupts ecological balance, because it increases soil acidity, thus affecting the land flora (plants) and fauna (animals). It also causes acidification of lakes and streams thus, affecting aquatic, crop productivity and finally, human health. Acidification kills many bacteria and blue-green algae (microorganisms) also.
