Official USCG Answer & Rule Citation
Correct Answer: Option A — can be observed visually from the other vessel
Rule 3(k) defines "in sight" strictly as visual observation. Radar detection, fog signals, or risk of collision assessments do not satisfy this definition. Visual contact is the threshold for applying steering and sailing rules for vessels in sight of one another.
