D
AI Explanation
The correct answer is A. Under the IALA-B Buoyage System, when entering from seaward a lateral system buoy to be left to starboard, the buoy may display a conical (nun) topmark as shown in illustration D046NG, option A. This topmark indicates that the buoy should be passed to the starboard (right) side when approaching from the sea. The other options, B, C, and D, represent different topmark shapes that would not be used for a starboard-hand lateral buoy in the IALA-B system. The key is that the conical (nun) shape in option A specifically denotes a starboard-hand buoy that should be passed to the right when entering from the seaward side.
