Best answer
Right answer is (c) Wound-rotor induction motor

The best explanation: DE series motor’s closest rival is the wound-rotor induction motor with a rotor resistance control. But ultimately the availability and economics of a dc power is the deciding factor rather than the motor characteristic.
