BOTH INTERNATIONAL & INLAND Which shape would a vessel aground show during daylight?

AI Explanation
The correct answer is C) Three black balls. According to the International Rules of the Road and the Inland Navigation Rules, a vessel aground during daylight must display three black balls in a vertical line. This signal indicates that the vessel is not under command and has restricted ability to maneuver, warning other vessels to keep clear. The other answer choices are incorrect because they do not match the standard signal for a vessel aground. One, two, or four black balls would not be the proper daylight signal to indicate a vessel aground.
