Question

CFCs are used for

• A. Air-conditioning
• B. Refrigeration system
• C. Both A and B
• D. T.V.

Answer 1

The correct option is C Both A and B

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 allowing the penetration of the harmful UV radiations from the sun into the Earth's atmosphere.

Thus, the correct answer is option C.
