A A
B B
C C
D D
AI Explanation

The correct answer is A. When entering from seaward, a buoy displaying a composite group (2+1) flash pattern indicates a special mark. According to the United States Coast Guard's Navigation Rules and Regulations, special marks are used to indicate a special area or feature, and they are colored yellow. The other options are incorrect because B is a port-side buoy, C is a starboard-side buoy, and D is a preferred channel buoy, none of which match the characteristics of a composite group (2+1) flash pattern buoy.
