BOTH INTERNATIONAL & INLAND What shape would a vessel at anchor show during daylight?

A One black ball
B Two black balls
C Three black balls
D No signal
AI Explanation

The correct answer is A) One black ball. According to the International and Inland Navigation Rules, a vessel at anchor during daylight must display one black ball in the forepart of the vessel. This signal indicates to other vessels in the area that the anchored vessel is stationary and not underway. The other answer choices are incorrect because a vessel at anchor would not display two or three black balls, and it would not display no signal at all.
