Question

CFCs used in refrigerators cause

• A. Water pollution
• B. Ozone depletion
• C. Acid rain
• D. Photochemical smog

Answer 1

The correct option is B Ozone depletion

The presence of CFCs in the atmosphere results in the depletion of the ozone layer. They are used as coolants in refrigerators, coolers, etc. The CFCs causes the breaking of the ozone molecule which forms the oxygen radical and O${}_2$. 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 B.
