Official USCG Answer & Rule Citation

Correct Answer: Option B — horizontally banded buoys

Horizontally banded buoys indicate preferred channels. In the IALA-B system, these buoys are colored red and green. If the top band is green, the buoy will display a green light. Spherical, yellow, and vertically striped buoys do not utilize green lights for channel marking purposes.
