D D
AI Explanation

The correct answer is B. The shape shown in illustration D016RR that would be used to indicate a vessel with a tow exceeding 200 meters in length is the square shape (B). This is in accordance with the International Regulations for Preventing Collisions at Sea (COLREGS), which require vessels with a tow exceeding 200 meters in length to display this square shape. The other shapes shown (A, C, and D) are not used to indicate a vessel with a tow exceeding 200 meters. They have different meanings, such as indicating a vessel constrained by its draft (A) or a vessel not under command (C and D).
