AI Explanation

The correct answer is D. The safe water mark, also known as a fairway buoy, is represented by the symbol D in the illustration. This buoy is used to mark the center of a navigable channel or fairway, indicating that it is safe for vessels to pass on either side. The other options (A, B, and C) represent different types of buoys, such as port and starboard side markers, which are used to delineate the edges of a channel and should not be crossed by vessels.
