The correct answer is: $\mathrm{Sn} / \mathrm{HCl}$
The most widely used method for preparing aromatic amines is the reduction of the nitro group to the amino group. This reduction can be achieved by catalytic hydrogenation, or most frequently with an acid and a metal (Fe, $\mathrm{Zn}, \mathrm{Sn})$ or a metal salt like $\mathrm{Sn} \mathrm{Cl}_{2}$.
