BOTH INTERNATIONAL & INLAND Which light(s) will be visible to a vessel overtaking another vessel?

A a sidelight and one masthead light of the vessel
B only a sidelight of the vessel
C only the stern light of the vessel
D any lights except the masthead lights of the vessel
AI Explanation

The correct answer is C) only the stern light of the vessel. According to the Navigation Rules, International and Inland, when a vessel is being overtaken by another vessel, the overtaking vessel should see the stern light of the vessel being overtaken. The stern light is the only light that is visible from the rear of the vessel, regardless of whether it is an international or inland navigation situation. The sidelights and masthead lights would not be visible to the overtaking vessel from the rear. The other answer options are incorrect because they do not accurately describe the lights that would be visible to the overtaking vessel.
