Correct option is C

Sol: The correct answer is (c) Carbon Monoxide (CO)

Key Points:

Carbon Monoxide (CO)

• Produced when coal and petroleum are burnt in insufficient air (oxygen).

• A highly toxic and harmful gas.

• Causes pollution and poses severe health risks, including carbon monoxide poisoning.

Information Booster:

A. Carbon Dioxide (CO₂)

• Produced during the complete combustion of coal and petroleum.

• A greenhouse gas contributing to global warming and climate change.

B. Oxides of Nitrogen (NOx)

• Formed during high-temperature combustion processes.

• Contribute to air pollution, acid rain, and respiratory problems.

D. Sulphur Dioxide (SO₂)

• Produced from burning coal and petroleum containing sulfur compounds.

• Contributes to air pollution and acid rain.

• Causes respiratory issues and environmental harm.
