Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Solubility of $A g C l$ in $N H_{3} (a q .)$ is greater than in pure water because when $A g C l$ dissolve in $N H_{3} (a q .)$ it will form complex ion with $A g^{+}$ and formation of $A g (N H_{3})_{2}^{+}$ takes place and because of this solubility equilibria of $A g C l$ shifted in forward direction and it dissolve more with respect to pure water.

$A g^{+} + 2 N H_{3} (a q) ⇋ [A g (N H_{3})_{2}]^{+}$
