Diagram for question 500
AI Explanation
The correct answer is D) White. When vessel "A" is overtaking vessel "B" in both international and inland navigation rules, vessel "B" will display a white stern light. This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS) and the United States Inland Navigation Rules. The other answer choices are incorrect because: A) Flashing red is the light displayed by the vessel being overtaken, not the overtaking vessel. B) Green is the sidelight displayed by the vessel being overtaken. C) Yellow over yellow is the light configuration for a towing vessel, not an overtaking situation.
