INTERNATIONAL ONLY What shape is prescribed for a vessel constrained by her draft?

AI Explanation
The correct answer is D) A cylinder. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel constrained by her draft is required to display a cylinder shape. This shape indicates that the vessel's draft prevents it from deviating from the course it is following. The other options are incorrect because they do not match the prescribed shape for a vessel constrained by her draft. A black cone, apex upward or downward, is used for different signals, and two vertical black balls are not the correct shape for this situation.
