C. Greenhouse gas
D. Primary pollutant



Answer :

Final answer:

Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides from fossil fuel combustion, resulting in harmful effects on the environment.


Explanation:

Acid rain is a term used to describe a mixture of wet and dry atmospheric deposition containing higher-than-normal levels of nitric and sulfuric acids. This phenomenon is primarily caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion. These gases react in the atmosphere to form acidic compounds, leading to the harmful effects associated with acid rain such as acidification of lakes, damage to vegetation, and corrosion of structures.
