The equations shown below each represent redox reactions. $\text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2$ $2\text{ZnO} + \text{C} \rightarrow 2\text{Zn} + \text{CO}_2$ $\text{Fe}_2\text{O}_3 + 2\text{Al} \rightarrow \text{Al}_2\text{O}_3 + 2\text{Fe}$ $2\text{CO} + 2\text{NO} \rightarrow 2\text{CO}_2 + \text{N}_2$ In these reactions, which oxide is oxidised?
- A$\text{Fe}_2\text{O}_3$
- B$\text{CO}$
- C$\text{ZnO}$
- D$\text{NO}$
