B. X: Rotates as a result of changing magnetic forces

Y: Conducts current to the armature and reverses direction of current

C. X: Allows current to flow into the commutator

Y: Conducts current to the armature and reverses direction of current

D. X: Allows current to flow into the commutator

Y: Rotates as a result of changing magnetic forces

Explanation:

Carbon brush is a motor brush that acts as the conducting block for current between the stator and the rotor of a motor. It is made of carbon blocks. The brush is held in place using a spring that ensures its contact position with the commutator. The commutator prevents the torque on the motor from reversing whenever the coil is rotating in the magnetic field.
