The correct answer is B) non-follow-up controller. When the Operation Selector Switch is in the "Controller" position, the non-follow-up controller is used to control rudder movement. The non-follow-up controller allows for direct, manual control of the rudder without any feedback or position indication, unlike a follow-up controller which provides continuous feedback on the rudder's position. The other options are incorrect because: A) the ship's steering wheel is not used when the selector switch is in the "Controller" position, C) the rate of turn signal does not directly control the rudder, and D) the gyrocompass provides heading information but does not directly control the rudder.
