The correct statement that explains the flow of energy through Ellen's motor is:
**A. battery --> electrical current --> copper wire rotor --> magnet --> mechanical energy.**
This choice accurately describes how the battery provides electrical energy, which flows through the copper wire rotor, creating a magnetic field that interacts with the magnet, ultimately resulting in mechanical energy (motion) of the rotor.
