Solution
The correct option is D A and C both are correct Answer is D. The strips of metals inserted in the electrolytes for conduction ofelectricity are called electrodes. The metal electrode connected to the positive terminal of the battery is called the anode (+). The metal electrode connected to the negative terminal of the battery is called the cathode (-) The anode is the electrode where oxidation occurs; the node loses electrons. The cathode is the electrode where reduction occurs; the node gains electrons. Hence, the statements A and C are correct.
