Question

Presence of CFCs in the atmosphere is responsible for

• A. Formation of ozone
• B. Production of healthy plants
• C. Depletion of ozone layer
• D. None of these

Answer 1

The correct option is C Depletion of ozone layer

CFCs are used as coolants in refrigerators, coolers, etc. The CFCs causes the breaking of the ozone molecule which forms the oxygen radical and O${}_2$. So, the presence of CFCs in the atmosphere results in the depletion of the ozone layer and allowing the penetration of the harmful UV radiations from the sun into the Earth's atmosphere.

Thus, the correct answer is option C.
