How does an electric motor convert electrical energy into mechanical energy?

I will post answer choices below

Answer 1

A.
When magnetism flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.

B.
When current flows through the motor, it powers electromagnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the electrical energy available.

C.
When mechanical energy flows through the motor, it powers electromagnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the electrical energy available.

D.
When current flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.
