Which line shows the symbol equation for the formation of carbon monoxide and for the reduction of iron(III) oxide in a blast furnace?
- A$2 ext{C} + ext{O}_2 ightarrow 2 ext{CO}$ ; $ ext{FeO} + ext{CO} ightarrow ext{Fe} + ext{CO}_2$
- B$ ext{CO}_2 + ext{C} ightarrow 2 ext{CO}$ ; $ ext{FeO} + ext{CO} ightarrow ext{Fe} + ext{CO}_2$
- C$ ext{C} + ext{O}_2 ightarrow ext{CO}_2$ ; $ ext{Fe}_2 ext{O}_3 + 3 ext{CO} ightarrow 2 ext{Fe} + 3 ext{CO}_2$
- D$ ext{CO}_2 + ext{C} ightarrow 2 ext{CO}$ ; $ ext{Fe}_2 ext{O}_3 + 3 ext{CO} ightarrow 2 ext{Fe} + 3 ext{CO}_2$
