(B) Step $1$: Aniline $(C_6H_5NH_2)$ reacts with $NaNO_2$ and $HCl$ at $0-5^{\circ}C$ to form Benzenediazonium chloride $(X = C_6H_5N_2^+Cl^-)$.Step $2$: Benzenediazonium chloride reacts with $CuCl/HCl$ (Sandmeyer reaction) to form Chlorobenzene $(Y = C_6H_5Cl)$.Step $3$: Chlorobenzene reacts with $CH_3Cl$ and $Na$ in the presence of dry ether (Wurtz-Fittig reaction) to form Toluene $(Z = C_6H_5CH_3)$.
