The correct answer is B) relatively high starting torque and low stator current. When a wound-rotor induction motor has maximum rheostat resistance inserted in the rotor circuit during starting, it results in a relatively high starting torque and low stator current. This is because the high resistance in the rotor circuit limits the rotor current, which in turn reduces the stator current drawn by the motor during starting. The high resistance also helps to increase the starting torque, as the torque of an induction motor is proportional to the rotor resistance during starting. The other options are incorrect because: A) would result in high starting torque and high stator current, C) would result in low starting torque and low stator current, and D) would result in low starting torque and high starting current, which is the opposite of the correct answer.
