AI Explanation
The correct answer is C. A vessel engaged in towing in fog shall sound a fog signal at intervals of not more than 2 minutes, not less than one minute. The International Regulations for Preventing Collisions at Sea (COLREGS) state that a vessel engaged in towing another vessel shall sound the fog signal for a power-driven vessel at intervals of not more than 2 minutes. This is to alert other vessels to the presence of the towing vessel and its tow. The other answer choices are correct statements about whistle signals.
