Assertion and Reasoning

Explanation:

The given assertion is true as chlorofluorocarbons (CFCs) are known to deplete the ozone layer. The ozone layer is a protective layer in the Earth's stratosphere that absorbs most of the sun's harmful ultraviolet (UV) radiation. CFCs were widely used as refrigerants, solvents, and propellants in aerosol sprays until they were banned under the Montreal Protocol in 1987. When CFCs are released into the atmosphere, they react with ozone molecules and break them down, leading to a depletion of the ozone layer.

The given reasoning is also true as CFCs are used as refrigerants and in fire extinguishers. However, this is not the correct explanation for why CFCs deplete the ozone layer. The reason for the depletion of the ozone layer due to CFCs is the chemical reaction between CFCs and ozone molecules, not their use in refrigerants and fire extinguishers.

Therefore, the correct answer is option A, where both assertion (A) and reason (R) are true, but reason (R) is the correct explanation of assertion (A).
