Answer: (A)

Burning of fossil fuels

Burning of fossil fuels is a man-made source of air pollution. The various fossil fuels like coal, natural gas, fuel oil are burned by humans for obtaining heat which is used in the generation of electric power. This leads to increase in the concentration of gas emissions like carbon dioxide and sulphur dioxide which enters the atmosphere and leads to air pollution. The increase in the concentration of carbon dioxide causes global warming and sulphur dioxide leads to breathing problem and the major cause of acid rain.
