(B) The reaction sequence is as follows:$1$. Aniline $(C_6H_5NH_2)$ reacts with $NaNO_2/HCl$ at $273-278 \ K$ to form benzenediazonium chloride $(C_6H_5N_2^+Cl^-)$.$2$. Benzenediazonium chloride reacts with $Cu_2Cl_2$ (Sandmeyer reaction) to form chlorobenzene $(C_6H_5Cl)$.$3$. Chlorobenzene reacts with $Na$ in the presence of dry ether (Wurtz-Fittig reaction) to form biphenyl $(C_6H_5-C_6H_5)$.
