Explanation:
All the answer choices listed only have 2-3 items in the electron configuration.
(2) Oxidation occurs as electrons are lost at the anode.(3) Reduction occurs as electrons are gained at the anode.
(4) Reduction occurs as electrons are lost at the cathode.
Oxidation occurs as electrons are lost at the anode at one of the electrodes in both an electrolytic cell and a voltaic cell. The answer is number 2. The rest of the choices does not answer the question given above.
