(A) The conversion of $p$-nitrophenol to quinol proceeds through the following steps:$1$. Reduction: $p$-nitrophenol is reduced using $Sn/HCl$ to form $p$-aminophenol.$2$. Diazotization: $p$-aminophenol is treated with $NaNO_2/HCl$ at $0-5 \ ^\circ C$ to form the corresponding diazonium salt.$3$. Hydrolysis: The diazonium salt is hydrolyzed by warming with water to yield quinol ($p$-dihydroxybenzene).
