The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Nitrogen exists as a diatomic gas because of the strong $p π - p π$ bonding present between two nitrogen molecules.
Well, a bonding in nitrogen is weak, hence catenation tendency is weaker in nitrogen.
