Question

Depletion of ozone layer is due to:

• A. ATP
• B. CFC
• C. NADP
• D. DDT

Hint:

CFCs cause ozone depletion by releasing chlorine, which destroys ozone molecules.

Answer 1

The Correct Option is B

Chlorofluorocarbons (CFCs) release chlorine atoms in the stratosphere, which break down ozone molecules, leading to depletion of the ozone layer.
Thus, the correct answer is \( \mathbf{(B) \text{CFC}} \).
