Answer:

C. X: Allows current to flow into the commutator

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

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.
