In a galvanic cell, the cathode is where reduction occurs.

Explanation:
In a galvanic cell, reduction occurs at the electrode where electrons are gained, while oxidation occurs at the electrode where electrons are lost. The electrons flow through the external circuit from the electrode that loses electrons to the one that gains them, driving the reduction at the cathode. So the cathode is the site of reduction and the anode is the site of oxidation, which is the best description of how a galvanic cell operates. The other statements conflict with this flow or with the roles of the electrodes, so they don’t accurately describe what happens in a galvanic cell.
