The Correct Option is B
Solution and Explanation
Step 1: Diazotization of aniline.
Aniline reacts with sodium nitrite and hydrochloric acid at \(273K\) to form benzene diazonium chloride.
\[ C_6H_5NH_2+NaNO_2+2HCl\rightarrow C_6H_5N_2^+Cl^-+NaCl+2H_2O \]
Step 2: Sandmeyer reaction.
Benzene diazonium chloride reacts with cuprous chloride to form chlorobenzene.
\[ C_6H_5N_2^+Cl^-\xrightarrow{Cu_2Cl_2}C_6H_5Cl+N_2 \]
Step 3: Coupling with sodium in dry ether.
Chlorobenzene reacts with sodium in dry ether to form biphenyl.
\[ 2C_6H_5Cl+2Na\xrightarrow{\text{dry ether}}C_6H_5-C_6H_5+2NaCl \]
Step 4: Final conclusion.
Thus, the major product formed is \[ \boxed{\text{Biphenyl}} \]
