Given below are two statements, one labeled as Assertion (A) and the other labeled as Reason (R). **Assertion (A):** Chlorofluorocarbons (CFCs) are highly stable and non-reactive in the troposphere, but they undergo rapid photolysis in the stratosphere. **Reason (R):** The stratosphere contains high-energy ultraviolet radiation (UV-C) that is capable of breaking carbon-chlorine bonds, which is mostly filtered out in the upper atmosphere and does not reach the troposphere. Choose the correct option:

Options:

• A: Both (A) and (R) are true and (R) is the correct explanation of (A)
• B: Both (A) and (R) are true but (R) is not the correct explanation of (A)
• C: (A) is true but (R) is false
• D: (A) is false but (R) is true
