What criteria might be used when selecting a buoy for marking?

When selecting a buoy for marking, visibility, location, and the type of hazard being marked are critical criteria. Visibility ensures that the buoy can be seen in various conditions by mariners, which is essential for safe navigation. The location determines where the buoy will be placed, influencing how it will be deployed and what kind of buoy is most effective for marking particular hazards or navigational points. Different types of hazards—such as shallow waters, wrecks, or safe channels—require specific buoy characteristics for proper indication, allowing mariners to navigate safely around these dangers. This makes option A the most comprehensive and relevant choice, as it addresses the key factors that affect the performance and safety of buoys in maritime environments.
