Which of the following reagents cannot be used to convert nitrobenzene to aniline?

H2/Pd-ethanol LiAlH4-dry ether Zn in HCl SnCl2/HCl

LiAlH4-dry ether

LiAlH4 may be used for the reduction of aliphatic nitro compounds to respective amines. But with aromatic nitro compounds (nitrobenzene), it gives azobenzene and not primary amines (aniline).
