A A
B B
C C
D D
AI Explanation

The correct answer is B. The shape shown in illustration D016RR that would be displayed on the after end of an inconspicuous partially submerged vessel or object being towed over 200 meters in length is a diamond shape (B). This is because the International Regulations for Preventing Collisions at Sea (COLREGS) require that a diamond shape be displayed on the after end of any vessel or object being towed that is 200 meters or more in length. This helps to make the towed object more visible to other vessels and prevent collisions. The other options (A, C, and D) are incorrect as they do not meet the COLREGS requirement for the appropriate shape to be displayed on a towed object over 200 meters in length.
