For which of the following metal, the carbon reduction cannot be used?

Metals at middle of the reactivity series like Zn, Pb,Fe are reduced by Carbon . Manganese, Mn is reduced by Al and Tungsten is reduced by hydrogen. Ex: ${\mathrm{Fe}}_2{\mathrm{O}}_3+3\mathrm{C}\to 2\mathrm{Fe}+3\mathrm{CO}$

${\mathrm{WO}}_3+3{\mathrm{H}}_2\stackrel{∆}{\to }\mathrm{W}+3{\mathrm{H}}_2\mathrm{O}; \mathrm{PbO}+\mathrm{C}\to \mathrm{Pb}+\mathrm{CO} 3{\mathrm{Mn}}_3{\mathrm{O}}_4+8\mathrm{Al}\stackrel{∆}{\to }4 {\mathrm{Al}}_2{\mathrm{O}}_3 +9\mathrm{Mn}$
