Answer 1

The correct option is D All of the above

CFCs are the molecules containing chlorine and fluorine. These compounds are used in the aerosols, foam formation, coolants in refrigerators, etc. The CFCs causes the breaking of the ozone molecule which forms the oxygen radical and O${}_2$. The depletion of the ozone layer results in the penetration of the harmful UV radiations from the sun into the Earth's atmosphere.

Thus, the correct answer is option D.
