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

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

Solution

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