(3); try using the phrase "AN OX ate the RED CAT"
(anode=oxidation, reduction=cathode)

Answer:  (3) at the anode in both an electrolytic cell and a voltaic cell

Explanation:  Electrolytic cells are the cells which convert electrical energy into chemical energy. For this purpose, 2 rods or electrodes are kept in the chemical solution. One is cathode and the other one is anode.

Anode is the electrode at which oxidation takes place and the sign of the electrode is positive and Cathode is the electrode at which reduction takes place and the sign of the electrode is negative.

Voltaic cells are the opposite of the electrolytic cell and both of the processes are same but the signs of the electrode are opposite. Anode is negatively charged and cathode is positively charged in this cell.

Thus option (3 is correct) as oxidation occurs at anode in both an electrolytic cell an voltaic cell.
