Yellow lights may appear on _______________.
AI Explanation
The correct answer is C) special purpose buoys.
Yellow lights are used on special purpose buoys, which are used to mark channels, anchorages, dredging operations, or other specific areas or objects. The International Association of Lighthouse Authorities (IALA) Buoyage System, which is used in the United States, specifies that yellow lights are reserved for special purpose buoys.
The other answer choices are incorrect because horizontally-banded buoys use white lights, spherical buoys use various colors depending on their purpose, and vertically-striped buoys use white lights.
