Explanation
Acid rain is primarily due to:
(B) Air Pollution.
Acid rain is a form of precipitation that contains high levels of sulfuric acid and nitric acid. It occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from various sources, such as industrial processes, power plants, and vehicles, mix with water vapor in the atmosphere. These pollutants undergo chemical reactions in the atmosphere and form acids, which then fall to the ground as acid rain. Therefore, acid rain is primarily caused by air pollution resulting from the release of sulfur dioxide and nitrogen oxides into the atmosphere.
