AI Explanation
The correct answer is C) actuating the throttle hand tripping device. The throttle hand tripping device is the primary method for stopping an auxiliary turbine boiler feed pump. This device is designed to quickly and safely shut down the turbine in an emergency, preventing damage to the equipment. Closing the exhaust valve slightly (A), rotating the hand lube oil pump backwards (B), or increasing the load on the driven unit (D) are not the correct procedures for normally stopping an auxiliary turbine boiler feed pump.
