Question 960 Rules of the Road

The correct answer is B) Three strokes of the bell before and after the rapid ringing of the bell. This signal is required by the Inland and International Rules of the Road to identify a vessel that is aground in addition to the regular anchor signals. The rapid ringing of the bell indicates the vessel's condition of being aground. The three strokes of the bell before and after the rapid ringing help draw attention to this signal. The other options are incorrect because A) refers to a gong signal, which is not the correct signal for an aground vessel, C) is a signal for getting attention but does not indicate the vessel's condition, and D) is incorrect as there are additional signals required beyond the regular anchor signals.
