Correct Answer: Option D — by applying torque in the opposite direction of rotation direction, the motor briefly regenerates power back into the mains, which rapidly slows down the motor

Regenerative braking occurs when the motor acts as a generator, converting kinetic energy into electrical energy. By applying torque in the direction opposite to rotation, the system forces the motor to slow down while feeding power back into the mains, a standard practice for rapid deceleration in electric drives.
