A vessel which is being assisted by an icebreaker would display a flag hoist consisting of the code numeral "4" when the vessel _______________.
AI Explanation
The correct answer is D) the vessel becomes icebound.
The International Code of Signals specifies that a vessel being assisted by an icebreaker should display the code numeral "4" when the vessel becomes icebound. This indicates to the icebreaker that the assisted vessel is no longer able to maneuver due to being trapped in ice. The other answer choices, such as the vessel stopping, receiving ice damage, or experiencing a drop in speed, do not specifically indicate the vessel becoming icebound, which is the condition that would prompt the display of the "4" flag hoist.
