This question consists of two statements, Assertion (A) and Reason (R). Candidates must evaluate these statements and select the correct option. **Assertion (A):** Catalytic converters installed in automobiles help in reducing the formation of photochemical smog. **Reason (R):** Catalytic converters convert nitrogen oxides (NOx) into nitrogen gas (N2) and unburnt hydrocarbons into carbon dioxide and water.

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.
