To create an electric motor, the student would most likely need **C. A permanent magnet**.
Electric motors typically function by using electromagnetism, where an armature (a coil of wire) creates a magnetic field when electricity flows through it. A permanent magnet can provide a steady magnetic field that interacts with the magnetic field produced by the armature, allowing the motor to rotate.
The other options (an iron nail or an electric generator) would not be necessary for building a basic electric motor from the materials listed. An iron nail could potentially be used, but it would not be essential like a magnet would be. An electric generator is unrelated to the task of building a motor.
