Question 848 Rules of the Road

The correct answer is D) All of the above. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in trawling, which is a type of commercial fishing, may exhibit any of the signal lights listed in the answer choices. These lights are used to indicate the vessel's activity and navigation status to other vessels in the area. The other options are incorrect because they do not encompass all the possible signal lights that a trawling vessel may exhibit. A trawling vessel may need to display different light configurations depending on the specific circumstances and the regulations in the area where it is operating.
