INTERNATIONAL ONLY Which signal is required to be sounded by a power-driven vessel ONLY?

AI Explanation
The correct answer is D) A signal meaning, "I am altering my course to starboard." This is the correct answer because the International Regulations for Preventing Collisions at Sea (COLREGS) require a power-driven vessel to sound one short blast to indicate that it is altering its course to starboard. This signal helps communicate the vessel's intentions to other vessels in the area, improving navigation safety. The other answer choices are incorrect because they do not represent the specific signal required for a power-driven vessel altering course to starboard under the COLREGS.
