Statement 5.

Explanation:

Mg(s) is the reducing agent, donating 2 electrons to the Cu2+ ion, thereby losing 2 electrons Mg2+ (oxidized).

Cu2+ is the oxidizing agent, stealing 2 electrons from the Mg(s), thereby becoming reduced in the process.

Reducing agents (a.k.a. reductants) become oxidized in the process of reducing a species. Oxidizing agents (oxidants) become reduced by convention.

Also, these agents are found on the reactants' side.
