Copper metal can be extracted from copper (II) oxide by displacing it with aluminum. This process is also known as the thermite reaction. Copper in copper (II) oxide will be reduced while aluminum will be oxidized, forming copper metal and aluminum oxide.  Provide the balanced equation for this reaction.

• A. CuO + 2 Al → Cu + AlO
• B. 2 CuO + 3 Al → 2 Cu + Al₃O₂
• C. 3 CuO + 2 Al → 3 Cu + Al₂O₃
• D. 3 Cu₂O + 2 Al → 6 Cu + Al₂O₃

Answer: (C)
