(C) $(C)$ Sandmeyer's reaction is the process where the diazonium group $(-N_{2}^{+}X^{-})$ is replaced by a halogen (like $-Cl$ or $-Br$) using the corresponding cuprous salt ($CuCl$ or $CuBr$) in the presence of its acid ($HCl$ or $HBr$). The chemical equation is: $Ar-N_{2}^{+}X^{-} \xrightarrow{CuCl / HCl} Ar-Cl + N_{2} \uparrow$
