When a discharged battery is being recharged, the site of oxidation is different than when the battery was discharging. This happens despite the fact that oxidation occurs at the anode in each case. What best explains this change in oxidation site?
The term oxidation always refers to the process occurring at the negative electrode.
The same type of reaction happens in each case.
The cathode in a discharging battery becomes the anode when the battery is recharging.
The reaction in a battery happens in the same direction in each case.

Answer:

The correct answer is the term oxidation always refers to the process occurring at the negative electrode.

Explanation:

In an electrochemical cell redox reaction occur because oxidation occur in the negative electrode or anode

On the other hand reduction reaction occur in the positive electrode or cathode.

During oxidation the metal acting as anode donates electron to be oxidized whereas during reduction the metal acting as cathode accept that donated electrons to get reduced.
