Which single-letter sound signal may be made only in compliance with the International Rules of the Road?
AI Explanation
The correct answer is A) D.
The D signal, which is a continuous sounding of a whistle or horn, may only be made in compliance with the International Regulations for Preventing Collisions at Sea (COLREGS), also known as the International Rules of the Road. The D signal is used to indicate a vessel is maneuvering with difficulty and requires the give-way vessel to take early and substantial action to avoid collision.
