(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

Explanation:

Nitrogen molecule has triple bond, whereas oxygen has double bond. N-N Bond length of N2 is shorter. Hence, it is difficult to break the triple bond of N2. Hence N2 is less reactive. Both A and R are true.
