A buoy functions primarily as an aid to navigation or to mark the location of an object in the water, making option C the correct choice. Buoys are used to indicate safe channels, hazards, and important navigational information to mariners. They can signify underwater dangers, guide vessels through narrow passages, or provide reference points for navigational purposes. By adopting standardized colors and shapes based on the International Association of Lighthouse Authorities (IALA) system, buoys play a crucial role in maritime safety.

Understanding the intended purpose of buoys helps mariners avoid potential hazards and follow prescribed routes through various bodies of water. This ensures safer navigation, especially for commercial vessels and recreational boaters.

Other potential functions, like marking speed limits or defining no-wake zones, are more specific and do not encompass the overall role of buoys within maritime navigation. While buoys can occasionally be involved in these specific scenarios, their primary purpose is to assist in navigation and indicate locations of interest or caution in the waterway. Additionally, mooring ships is a different function, typically handled by other structures or systems designed explicitly for securing vessels.
