Correct Option A
The Assertion is true. Nitric oxide is a colorless gas at room temperature because it does not absorb light in the visible region of the electromagnetic spectrum. The Reason is also true and provides the correct explanation for the Assertion. Nitric oxide does not absorb light in the visible region of the electromagnetic spectrum because it does not have any unpaired electrons in its molecular orbitals. Therefore, it does not cause any complementary color to be observed. 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.
