Question 762 Rules of the Road

The correct answer is A) underway. The lights displayed in illustration D052RR indicate that the vessel is underway at night. The illustration shows a vessel displaying a masthead light, sidelights, and a stern light - which is the standard lighting configuration for a vessel underway as per the International Regulations for Preventing Collisions at Sea (COLREGS). The other answer choices are incorrect because: B) pushing ahead and C) towing a submerged object would require different lighting configurations, while D) engaged in dredging would typically display different signals to indicate the restricted nature of the vessel's operations.
