Solution

The correct option is A $F e_{2} O_{3}$
Alumino thermite process: Certain Oxides of $M n, T i, C r$ can not be reduced by carbon due to very high melting point. They are reduced by $A l$ .
So thermite is not used for reduction of iron oxide as it is reduced by $C O$ as follows:
$F e_{2} O_{3} + 3 C O \to 2 F e + 3 C O_{2}$
