A A mine clearance vessel while underway
B An overtaking vessel in a narrow channel
C A fishing vessel
D A vessel anchored
AI Explanation

The correct answer is B) An overtaking vessel in a narrow channel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), Rule 34(c), an overtaking vessel in a narrow channel is required to sound two prolonged blasts followed by one short blast on the whistle. This signal indicates the overtaking vessel's intention to pass the vessel being overtaken. The other options are incorrect because: A) a mine clearance vessel is not required to sound this signal, C) a fishing vessel is not required to sound this specific signal, and D) a vessel at anchor is not required to sound any signals.
