Correct Answer: Option A — 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's controller applies a reverse rotating magnetic field torque, forcing the motor to act as a generator and feed kinetic energy back into the distribution bus to rapidly decelerate the propeller shaft.
