Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Solubility of AgCN in acidic solution is greater than that in pure water
$A g C N + H A ⇋ H C N + A g^{+}$

and because of this reaction and formation of HCN, reaction shifts forward and solubility increases.
