Which part will surely tell that given motor is DC motor and not an AC

1.	Which part will surely tell that given motor is DC motor and not an AC type?(a) Winding(b) Shaft(c) Commutator(d) StatorThe question was asked during an interview.I would like to ask this question from DC Motor Basics -1 in division DC Motors of DC Machines
Answer» The correct answer is (c) Commutator Explanation: All other parts except brushes and commutator are same in AC MACHINE when outer LOOKS are only TAKEN in consideration. Commutator is USED only in DC machine for providing mechanical rectification and not in AC machine.
