Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$N_{3} H + N H_{3} ⇌ N_{3}^{-} + N H_{4}^{+}$
Here, ammonia accepts $H^{+}$ so its a base and $N_{3} H$ losses $H^{+}$ so its an acid.

So, this is proton-donor acceptor equilibrium.

Option A is correct.
