Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Bond energy of $N_{2}$ is very high so a large amount of heat is required for breaking $N_{2}$ bond. But, less amount of heat is released during the formation of $N O$ bond. Hence, the given conversion is endothermic in nature.

Hence, the assertion is correct and it is the correct explanation.
