(B) In the blast furnace,the reduction of iron oxides ($Fe_2O_3$ and $Fe_3O_4$) occurs primarily by $CO$ gas at lower temperatures $(500-800 \ K)$.The reaction is: $Fe_2O_3 + 3CO \rightarrow 2Fe + 3CO_2$.At higher temperatures $(> 1073 \ K)$,carbon $(C)$ also acts as a reducing agent,but $CO$ is the primary reducing agent in the upper cooler parts of the furnace.
