C C
D D
AI Explanation

The correct answer is A. According to the Inland Navigation Rules, the lights shown in illustration D085RR indicate a vessel crossing a channel or fairway. In this situation, you should pass the vessel displaying these lights on the side indicated by the flashing light - in this case, the side indicated by the light at position A. The other options are incorrect because B, C, and D do not correspond to the side indicated by the flashing light, which is the proper side to pass the vessel.
