A Give-way to the other vessel.
B Maintain course and speed as the ship is on your port bow.
C Sound the danger signal.
D Increase speed and cross his bow.
AI Explanation

The correct answer is A) Give-way to the other vessel. The reason this is the correct answer is that under both the International and Inland Navigation Rules, vessel "B" is the give-way vessel because vessel "A" is on its port bow and is constrained to the channel. Vessel "B" must take early and substantial action to keep well clear of vessel "A" by either slowing down, stopping, or altering course to starboard. Options B, C, and D would be incorrect actions that would violate the navigation rules.
