Answer:

C.   Mg → Mg²⁺ + 2e−

Explanation:

The oxidation reduction reactions are called redox reaction. These reactions are take place by gaining or losing the electrons and oxidation state of elements are changed.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

Consider the following reactions.

Mg + CuSO₄      →    MgSO₄  + Cu

Mg atom lose two electron and gets oxidized.

Mg → Mg²⁺ + 2e−

These two electrons are accepted by Cu and gets reduced.

CuSO₄       →      Cu²⁺ + SO₄²⁻

Cu²⁺ + 2e⁻   →  Cu
