DNFU
AI Explanation
The correct answer is D) NFU. When the operation selector switch is in the NFU (Non-Follow-Up) position, fine adjustments such as the "rate of turn signal" have no effect on the steering stand operation. In the NFU mode, the steering stand is disconnected from the autopilot or other automatic control systems, and the helm is directly controlling the rudder, making fine adjustments irrelevant. The other options (DIFF, HAND, and GYRO) are incorrect because they involve different steering modes that would be affected by fine adjustments to the system, unlike the NFU mode where the helm has direct manual control.
