Answer:
The correct answer is (C) Reduction.
Reduction reaction takes place at the cathode whereas oxidation reaction takes place at the anode.
Explanation:
The cathode is positively charged and the metal electrons are deposited here. As it gains electrons, the reduction is said to take place.
Exactly the opposite happens in case of the anode which is negatively charged and therefore acts as a source of electrons, i.e. electrons are lost from this electrode( hence oxidized).
