(C) The reaction $CH_3COCl + 2NH_3 \rightarrow CH_3CONH_2 + NH_4Cl$ is an example of nucleophilic acyl substitution. The Assertion is correct because $NH_3$ acts as a nucleophile to replace the $Cl$ atom.However,the Reason is incorrect. While $Cl^{-}$ is indeed a good leaving group,it is a very weak nucleophile compared to $NH_3$. The strength of a nucleophile is generally inversely related to the strength of its conjugate acid. Since $HCl$ is a strong acid,$Cl^{-}$ is a weak base and a weak nucleophile.

Assertion: $CH_3COCl$ is converted to $CH_3CONH_2$ on reaction with $NH_3$.
Reason: $Cl^{-}$ is a stronger nucleophile and better leaving group.
