The correct choice is (a) Commutator

The explanation: A typical brushless motor has permanent magnets which rotate around a fixed armature. An electronic controller replaces the brush-commutator assembly of the brushed conventional DC motor, which continually switches the phase to the windings to keep the motor turning.
