Solution

The correct option is A
When metallic oxides like lead oxide, iron oxide, zinc oxide are mixed with powered charcoal and heated strongly, they get reduced to their respective metals. In the above given equation iron oxide reacts with powdered charcoal in the presence of heat to obtain iron and carbon monoxide. So, carbon monoxide is the correct answer, in order to balance the equation we get 3CO.
