Answer: The correct answer is copper is getting reduced.
Step-by-step explanation:
Oxidation reaction is defined as the reaction in which an atom looses its electrons. Here, oxidation state of the atom increases. These reaction are shown by reducing agents.
Reduction reaction is defined as the reaction in which an atom gains electrons. Here, the oxidation state of the atom decreases. These reactions are shown by oxidizing agents.
For the given chemical reaction:
Here, copper atom is gaining 2 electrons to form copper metal. Thus, it is undergoing reduction reaction and is getting reduced.
