The above conversion can be carried out by

\mathrm{\left ( i \right )Sn-HCl}
\mathrm{\left ( i ii\right )Fe-HCl}
\mathrm{\left ( i v\right )Zn-HCl}
\mathrm{\left ( v\right )H_{2}-Pd}
\mathrm{\left ( vi\right )H_{2}- Raney\; Ni}

\mathrm{S{n}-NH_{4}OH} does not reduce Nitrobenzene to aniline.

Hence ,the answer is 5.
