Which equation shows a reaction that occurs when iron is extracted from its ore in the blast furnace?
- A$\text{CaO} + \text{SiO}_2 \rightarrow \text{CaSiO}_3$
- B$\text{CaO} + \text{CO}_2 \rightarrow \text{CaCO}_3$
- C$2\text{CO} \rightarrow \text{C} + \text{CO}_2$
- D$2\text{Fe} + 3\text{CO}_2 \rightarrow \text{Fe}_2\text{CO}_3 + 3\text{CO}$
