Question 969 Rules of the Road

The correct answer is A) A vessel 150 meters in length at anchor. The rapid ringing of a bell followed by the sounding of a gong for about five seconds each is the signal used by a vessel 150 meters or more in length while at anchor, as per the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules. The other options are incorrect because: B) a vessel aground would use a rapid ringing of a bell, C) a vessel engaged in fishing at anchor would use a single stroke of the bell every minute, and D) a sailing vessel at anchor would use a single stroke of the bell every minute.
