Solution

The correct option is D

24


Elemental metallic Aluminium carries an oxidation number of 0.
From the products, we see that 0Al becomes 3+Al3+.
Clearly, Aluminium is the reducing agent.

There are 8 Aluminium atoms on the left and they all become Al3+.
So overall, there are 24 electrons transferred.
