The correct option is A All
A:Fe2O3+CFe+CO2
B:ZnO+CZn+CO2
C:SnO2+CSn+CO2
D:PbO+CPb+CO2

Carbon can be used to reduce the oxides of metals below aluminum in the Reactivity Series.
Since Fe,Zn,Sn,Pb are found below aluminum in reactivity series, therefore carbon can reduce all of them.
Hence, all of the given reduction processes given are correct.
