Q.	The synchronous motor is not inherently self-starting because
A.	the force required to accelerate the rotor to the synchronous speed in an instant is absent
B.	the starting device to accelerate the rotor to near synchronous speed is absent
C.	a rotating magnetic field does not have enough poles
D.	the rotating magnetic field is produced by only 50 Hz frequency currents
