Answer
alumina is not reduced by reducing agents.
Reason — Electrolytic reduction is chosen as the method for reducing alumina. Since, aluminium oxide due to its great affinity for oxygen is a very stable compound. It is not reduced easily by common reducing agents like carbon, carbon monoxide or hydrogen.
