A Octagonal
B Triangular
C Circular
D Diamond
AI Explanation

The correct answer is A) Octagonal. Safe water daymarks are octagonal in shape, as per the U.S. Aids to Navigation System. This distinctive shape helps boaters identify them as marks indicating safe, open water. The octagonal shape differentiates safe water daymarks from other types of navigation marks, such as triangular channel markers or circular buoys. The octagonal shape is a key identifying feature that helps mariners recognize safe water daymarks and navigate safely.
