Spoil grounds, anchorage areas, cable areas, and military exercise areas are all marked by yellow buoys. Which special mark on the buoy will indicate the specific area you are in?

Correct Answer: Option D — Lettering on the buoy

Special marks such as yellow buoys utilize specific lettering stenciled on their hulls to explicitly denote the exact nature of special areas like spoil grounds, anchorage areas, or cable zones, rather than relying on geometric topmarks.
