Which region uses Green Right Returning buoyage?

Green Right Returning is a regional convention within the IALA buoyage system. It tells you which side of the channel green marks appear when you are returning to port. In the region used for this question, that convention is assigned to Region A. So when you are navigating in this region, green lateral marks are on the starboard side on the returning leg, indicating the safe channel lies to the opposite side as you come back toward port. This makes Region A the correct match for Green Right Returning in the context of the question. Remember that other regions use different color conventions, so if you’re in a different region you must reinterpret the marks according to that region’s rules, using chart information, topmarks, and light characteristics to stay on the correct side.
