Solution

The correct option is C $F e_{2} O_{3}$
Wrought iron or malleable iron is the purest form of commercial iron and is prepared from cast iron by oxidising impurities in a reverberatory furnace lined with haematite. The haematite oxidises carbon to carbon monoxide:
$F e_{2} C O_{3} + 3 C \to 2 F e + 3 C O$
Hence, option $C$ is the correct answer.
