AI Explanation
The correct answer is C) securing the fuel supply. The main propulsion diesel engine in a vessel is normally shutdown by securing the fuel supply to the engine. This is the primary method for shutting down a diesel engine, as cutting off the fuel source will stop the combustion process and cause the engine to stop running.
