As we have learnt,

By Reducing of Nitro Compounds -

Nitro group is reduced to NH2  group by Sn + HCl, Fe + HCl or by catalytic hydrogenation.

\mathrm{CH_{3}-CH_{2}-NO_{2}\overset{H_{2}/Ni}{\longrightarrow}CH_{3}CH_{2}NH_{2}}

\mathrm{CH_{3}-CH_{2}-NO_{2}\xrightarrow[\Delta ]{Sn+Conc.HCl}CH_{3}CH_{2}NH_{2}}

\mathrm{CH_{3}-CH_{2}-NO_{2}\xrightarrow[\Delta ]{Fe+Conc.HCl}CH_{3}CH_{2}NH_{2}}

All of the above can be used for the purpose.

Hence, the correct answer is Option (2)
