Solution:

The correct answer is: Sulphur and Nitrogen

Acid rain is caused by the emission of pollutants, primarily:

1. Sulfur dioxide (SO2)
2. Nitrogen oxides (NOx)

These pollutants react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid and nitric acid, leading to acid rain.

Sulfur dioxide comes from:

• Burning fossil fuels (coal, oil, and gas)
• Industrial processes (smelting, refining)

Nitrogen oxides come from:

• Burning fossil fuels (especially vehicles)
• Industrial processes
• Agricultural activities

Acid rain can harm the environment, infrastructure, and human health.

The other options are not the primary causes of acid rain:

• Carbon is a component of many pollutants, but it’s not directly responsible for acid rain.
• Phosphorus is not typically associated with acid rain formation.
