Question 781 Rules of the Road

The correct answer is B) A power-driven vessel less than 50 meters in length with a 20-meter tow. According to the International and Inland Navigation Rules, a power-driven vessel less than 50 meters in length that is towing another vessel astern must display two masthead lights in a vertical line. This requirement applies when the length of the tow, including the length of the towing vessel, exceeds 200 meters. The other options are incorrect because they do not meet this specific requirement for a power-driven vessel under 50 meters with a tow exceeding 200 meters in total length.
