Assertion : Nitrogen and Oxygen are the main components in the atmosphere but these do not react to form oxides of nitrogen. Reason : The reaction between nitrogen and oxygen requires high temperature.

1. Both assertion and reason are correct, and the reason is the correct explanation for the assertion
2. Both assertion and reason are correct, but the reason is not the correct explanation for the assertion
3. The assertion is incorrect, but the reason is correct
4. Both the assertion and reason are incorrect

Correct answer: Both assertion and reason are correct, and the reason is the correct explanation for the assertion

Solution

The assertion is accurate as nitrogen and oxygen are indeed the primary components of the atmosphere, and they do not readily react under normal conditions. The reason is also correct because the formation of nitrogen oxides typically requires high temperatures, such as those found in combustion processes, which explains why these gases do not form spontaneously in the atmosphere.
