Nitrobenzene is reduced with $Zn$ and aqueous $NH X_{4} Cl$ to give Y. Y is then warmed with dilute $H X_{2} SO X_{4}$ to give Z as the major product. Z is

A2-aminophenol
B4-aminophenol
Caniline
Dazoxybenzene

Answer: B

Neutral reduction gives N-phenylhydroxylamine (Y). In warm dilute acid, Y undergoes the Bamberger rearrangement: the protonated hydroxylamine loses water to give a nitrenium-type ion that is attacked by water mainly at the para position, giving 4-aminophenol.
