Air pollution is the contamination of the air and its surroundings due to air pollutants. Chlorofluorocarbons (CFCs) are most likely a source of air pollution. Thus, option B is correct.
What are Chlorofluorocarbons?
Chlorofluorocarbons (CFCs) are nontoxic chemicals that contain chlorine, fluorine, and carbon. They are largely used in the manufacturing of refrigerants, foams, sprays, etc.
Chlorofluorocarbons destroy the protective ozone layer of the earth and affect its ability to shield the harmful UV rays from the sun. Due to their dangerous effect on the ozone, they are banned.
They are emitted and get deposited in the earth's atmosphere causing the greenhouse effect that causes the melting of the ice and increases in the sea level to rise in temperature.
Therefore, chlorofluorocarbons are the source of air pollution.
