(B) The reaction between benzenediazonium chloride and phenol in a weakly basic medium is a coupling reaction. In this reaction,the diazonium group $(-N=N-)$ replaces the hydrogen atom at the para-position of the phenol ring. The product formed is $p$-hydroxyazobenzene,which is an orange-red dye. The reaction is: $C_6H_5N_2Cl + C_6H_5OH \xrightarrow{OH^-} C_6H_5-N=N-C_6H_4OH + HCl$.
