In power plant sulphur dioxide is produced by combustion of this fuel

Correct option is A

Correct Answer: (a)
Explanation
Sulphur dioxide (SO₂} is mainly produced when coal containing sulphur impurities is burned in thermal power plants.
Reaction: S + O₂ → SO₂
SO₂ is a major air pollutant and is responsible for:
· Acid rain
· Respiratory diseases
· Damage to crops and buildings
Hence, the correct answer is Option (a}: Coal.
Additional Information
Major pollutants from coal-fired thermal power plants:
· Sulphur dioxide (SO₂}
· Carbon dioxide (CO₂}
· Nitrogen oxides (NOₓ}
· Fly ash and particulate matter
Remember: Coal → SO₂ → Acid Rain
