The figure shows the electrolysis of molten AlCl 3 .What reaction occurs at the cathode of this cell?

At the cathode, the aluminum ion (Al3+) gains 3 electrons to form neutral aluminum metal (Al), according to the half-reaction: Al3+ + 3e- -> Al This is the only option that includes a reduction half-reaction involving aluminum. All the other options involve either the reduction of chlorine or no reduction reaction at all.
