(A) The given reaction is a nucleophilic acyl substitution reaction. The rate of this reaction depends on the leaving group ability of $Z^-$. $A$ better leaving group makes the reaction faster. The leaving group ability is inversely proportional to the basicity of the group. Among the given options,$Cl^-$ is the weakest base and thus the best leaving group. Therefore,the reaction is fastest when $Z = Cl$.
