______ And________are the primary causes of acid rain.

Correct option is B

Acid rain is caused by acidic oxides in the atmosphere.
Sulphur dioxide reacts with water to form sulphuric acid.
Nitrogen oxides form nitric acid in the atmosphere.
These acids fall as acid rain affecting soil and water bodies.
CO₂ causes weak carbonic acid, not acid rain.
Therefore, SO₂ and NOx are the correct answer.
