JEE Main 2015 Chemistry question

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 the Assertion and Reason are incorrect.
(2)Both Assertion and Reason are correct and the Reason is the correct explanation for the Assertion.Correct
(3)Both Assertion and Reason are correct, but the Reason is not the correct explanation for the Assertion.
(4)The Assertion is incorrect but the Reason is correct.
