10. One group of gases that is responsible for destroying ozone in the ozone layer is

A.car exhaust fumes
B.CFCs
C.nitrogen oxides and sulfur oxides
D. Carbon monoxide and carbon dioxide

I got B for my answer.

Right.

Your answer is correct. The group of gases that is responsible for destroying ozone in the ozone layer is B. CFCs (chlorofluorocarbons).

CFCs are synthetic compounds made up of chlorine, fluorine, and carbon atoms. They were widely used in various applications such as air conditioning, refrigeration, aerosol propellants, and foam-blowing agents.

To arrive at the correct answer, one can eliminate the other options:

A. Car exhaust fumes primarily contribute to air pollution but do not significantly deplete the ozone layer.

C. Nitrogen oxides (NOx) and sulfur oxides (SOx) are pollutants that contribute to acid rain and smog but are not major contributors to ozone depletion.

D. Carbon monoxide (CO) and carbon dioxide (CO2) are greenhouse gases that contribute to global warming; however, they do not directly harm the ozone layer.

To determine the answer, it is essential to have knowledge about the impact of different gases on the ozone layer and their sources. In this case, understanding the properties and usage of CFCs helped to identify the correct answer.
