A A
B B
C C
D No day-shape would be shown.
AI Explanation

The correct answer is B. According to the International Regulations for Preventing Collisions at Sea (COLREGS), an inconspicuous partially submerged vessel or object being towed less than 200 meters in length is required to display a diamond shape on the after end. This is specified in Rule 24(c) of the COLREGS. The other answer choices are incorrect because: A) A diamond shape is the correct shape, not a single ball. C) A diamond shape, not a double cone, is the required day-shape. D) A day-shape must be displayed, not no shape at all.
