Reactivity series — practice question

Iron is obtained from $\text{Fe}_2\text{O}_3$ by reducing it with carbon. It is hard to extract aluminium from $\text{Al}_2\text{O}_3$. Electrolysis is required for this process. Beginning with the most reactive, which reactivity order is correct?

  • A$\text{Al} \rightarrow \text{C} \rightarrow \text{Fe}$
  • B$\text{Al} \rightarrow \text{Fe} \rightarrow \text{C}$
  • C$\text{Fe} \rightarrow \text{Al} \rightarrow \text{C}$
  • D$\text{Fe} \rightarrow \text{C} \rightarrow \text{Al}$
