Which buoy may be even numbered?
AI Explanation
The correct answer is A) Unlighted nun buoy.
Unlighted nun buoys may be even-numbered as they mark the port (left) side of a channel when entering from seaward. This is in accordance with the United States Aids to Navigation System (USATONS) which dictates that even-numbered buoys mark the port side of a channel. The other options (B, C, and D) are incorrect because mid-channel buoys, lighted green buoys, and all buoys are not necessarily even-numbered under the USATONS.
