The correct answer is:
$\mathrm{Fe}_2 \mathrm{O}_3+\mathrm{CO} \rightarrow 2 \mathrm{FeO}+\mathrm{CO}_2$
At $900-1500 \mathrm{~K}$ (higher temperature range in the blast furnace)
Reaction which take place are:
$\mathrm{C}+\mathrm{CO}_2 \longrightarrow 2 \mathrm{CO}$
$\mathrm{FeO}+\mathrm{CO} \longrightarrow \mathrm{Fe}+\mathrm{CO}_2$
$\mathrm{CaO}+\mathrm{SiO}_2 \longrightarrow \mathrm{CaSiO}_3$ (Slag formation)
$\mathrm{Fe}_2 \mathrm{O}_3+\mathrm{CO} \longrightarrow 2 \mathrm{FeO}+\mathrm{CO}_2$ at $500-800 \mathrm{~K}$
Reaction which take place are:
$\mathrm{C}+\mathrm{CO}_2 \longrightarrow 2 \mathrm{CO}$
$\mathrm{FeO}+\mathrm{CO} \longrightarrow \mathrm{Fe}+\mathrm{CO}_2$
$\mathrm{CaO}+\mathrm{SiO}_2 \longrightarrow \mathrm{CaSiO}_3$ (Slag formation)
$\mathrm{Fe}_2 \mathrm{O}_3+\mathrm{CO} \longrightarrow 2 \mathrm{FeO}+\mathrm{CO}_2$ at $500-800 \mathrm{~K}$
