The metal whose oxide, which is amphoteric, is reduced to metal by carbon reduction ___________. $(Fe/Mg/Pb/Al)$.

The metal whose oxide, which is amphoteric, is reduced to metal by carbon reduction PbPb.
Amphoteric substances reacts with acids as well as bases.
$PbO+2HN{O}_3\to Pb(N{O}_3{)}_2+H_{2}O$
$PbO+2NaOH\to N{a}_{2}Pb{O}_2+H_{2}O$

On heating with carbon, $PbO$ is reduced to Pb.
$PbO+C\to Pb+CO$
$PbO+CO\to Pb+C{O}_2$
