Correct option is C
The correct answer is (c) Nitrogen oxides.
· Nitrogen oxides (NOx), along with sulphur dioxide (SO₂), are major contributors to acid rain. These gases are released into the atmosphere mainly from burning fossil fuels in vehicles, industries, and power plants.
· When nitrogen oxides and sulphur dioxide react with water vapor in the atmosphere, they form nitric acid (HNO₃) and sulfuric acid (H₂SO₄), respectively. These acids then mix with rainwater, resulting in acid rain.
· Acid rain can harm ecosystems, damage buildings, and degrade soil and water quality.
· Nitrogen oxides are also a major component of photochemical smog and contribute to air pollution.
Information Booster:
· Carbon dioxide (CO₂) contributes to global warming but is not a significant cause of acid rain.
· Carbon monoxide (CO) is a harmful gas but does not directly contribute to acid rain.
· Oxygen and Hydrogen: These are not directly involved in causing acid rain.
