AI Explanation
The correct answer is D) horizontally banded buoys.
Red lights may appear on horizontally banded buoys, which are used to mark the edges of channels or as regulatory markers. According to the U.S. Coast Guard's Aids to Navigation System, red lights are commonly used on the top or middle band of these types of buoys to indicate the limits of a navigable channel or to convey regulatory information.
