Choose the correct sequence of reagents in the conversion of 4-nitrotoluene to 2 -bromotoluene.

$\mathrm{Br}_2 ; \mathrm{Sn} / \mathrm{HCl} ; \mathrm{NaNO}_2 / \mathrm{HCl} ; \mathrm{H}_2 \mathrm{O} / \mathrm{H}_3 \mathrm{PO}_2$
$\mathrm{Sn} / \mathrm{HCl} ; \mathrm{Br}_2 ; \mathrm{NaNO}_2 / \mathrm{HCl} ; \mathrm{H}_2 \mathrm{O} / \mathrm{H}_3 \mathrm{PO}_2$
$\mathrm{NaNO}_2 / \mathrm{HCl} ; \mathrm{Sn} / \mathrm{HCl} ; \mathrm{Br}_2 ; \mathrm{H}_2 \mathrm{O} / \mathrm{H}_3 \mathrm{PO}_2$
$\mathrm{Sn} / \mathrm{HCl} ; \mathrm{NaNO}_2 / \mathrm{HCl} ; \mathrm{Br}_2 ; \mathrm{H}_2 \mathrm{O} / \mathrm{H}_3 \mathrm{PO}_2$
