Detailed Solution

In a redox reaction, the substance that either gains oxygen or loses hydrogen is oxidised. On the other hand, the substance that loses oxygen or gains hydrogen is reduced.

In the given reaction, aluminium gains oxygen to form aluminium oxide. Hence, aluminium is oxidised. Ferric oxide (Fe₂O₃) loses oxygen to form iron (Fe). Hence, Fe₂O₃ is reduced in the given process.
