Final answer:
A Constant Speed Drive (option B) would move the driven device at the same speed as the motor.
Step-by-step explanation:
The type of drive that would move the driven device at the same speed as the motor is a Constant Speed Drive (option B).
A Constant Speed Drive, as the name suggests, enables the driven device to operate at a constant speed that matches the speed of the motor. This type of drive is commonly used in applications where precise speed control is not required, and maintaining a consistent speed is important.
For example, in a scenario where a motor is used to power a conveyor belt in a factory, a Constant Speed Drive would ensure that the conveyor belt always moves at the same speed as the motor.
