Correct Option A 

The Assertion is true. Nitrogen oxides are major contributors to acid rain because the reaction of nitrogen oxides with water in the atmosphere contributes to acid rain. The Reason is also true and provides the correct explanation for the Assertion. Nitrogen oxides, especially nitrogen dioxide \mathrm{\left ( NO_{2} \right )}, react with water in the atmosphere to form nitric acid, which is a major contributor to acid rain. The reaction is represented as follows:

\mathrm{NO_{2}+H_{2}O\rightarrow HNO_{3}}

Hence option A is the correct answer.

Option (B) is incorrect because it incorrectly states that the assertion is correct but the reason is incorrect. Both the assertion and reason are correct. Hence option B is incorrect.

Option (C) is incorrect because it incorrectly states that the assertion is incorrect but the reason is correct. The assertion is correct, and the reason is also correct. Hence option C is incorrect.

Option (D) is incorrect because it incorrectly states that both the assertion and reason are incorrect. Both the assertion and reason are correct. Hence option D is incorrect.
