The light in this diagram is producing light.

which best describes the process of energy conversion to accomplish this?

a.
electrical energy turns the rod. this energizes the coil. the magnetized coil generates an electric current. the electric current goes through the wires to power the lightbulb.

b.
mechanical energy turns the rod. this electrifies the coil. the electrified coil generates a magnetic field. the magnetic field goes through the wires as electricity to power the lightbulb.

c.
mechanical energy turns the rod. this magnetizes the coil. the magnetized coil generates an electric current. the electric current goes through the wires to power the lightbulb.

d.
the magnetic energy in the coil turns the rod. the rod generates an electric current. the electric current goes through the wires to power the lightbulb.
