(C) $1$. Aniline reacts with $Br_2/H_2O$ to form $2,4,6$-tribromoaniline $(X)$.$2$. $2,4,6$-tribromoaniline reacts with $NaNO_2/HCl$ at $273-278 \ K$ to form the diazonium salt,$2,4,6$-tribromobenzenediazonium chloride $(Y)$.$3$. The diazonium salt $(Y)$ reacts with ethanol $(C_2H_5OH)$ to undergo reduction,where the diazonium group is replaced by a hydrogen atom,yielding $1,3,5$-tribromobenzene $(Z)$.
