A. A spherical buoy
B. An unlighted can buoy
C. A red buoy
D. A yellow buoy
Final answer: The correct option is C. A red buoy.
Answer:
The correct option is C. A red buoy. The red buoy may be odd numbered according to the U.S. Aids to Navigation System, which uses odd numbers for red buoys and conforms to the 'red right returning' rule.
Explanation:
The answer to the question "Which buoy may be odd numbered?" is C. A red buoy.According to the U.S. Aids to Navigation System (ATON), the navigational aids mark the edges of safe water areas and are colored and numbered so that a mariner can identify them on a chart and determine direction and progress. The system uses odd numbers for red buoys and even numbers for green buoys. This is in accordance with the 'red right returning' rule, meaning that the red buoys should be on the right side (starboard) of the boat when returning to harbor, and therefore, would be odd-numbered.
Based on this information, the odd numbered buoy would be an unlighted can buoy (Option B). The reason is that unlighted can buoys are typically used to mark the port (left) side of a channel when entering from the sea. They are cylindrical-shaped and painted in black color. Unlike spherical buoys (Option A), which are evenly shaped and may be used to mark the starboard (right) side of a channel, or colored buoys such as red (Option C) or yellow (Option D) which have specific meanings, an unlighted can buoy does not follow the usual pattern and can be considered odd numbered.
