Answer:

Statement 5.

Explanation:

#"Mg"(s)# is the reducing agent, donating #2# electrons to the #"Cu"^(2+)# ion, thereby losing #2# electrons #-># #"Mg"^(2+)# (oxidized).

#"Cu"^(2+)# 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.
