A special mark (yellow buoy), if lighted, may exhibit which light rhythm?

A Morse "A"
B Equal interval
C Flashing
D Occulting
AI Explanation

The correct answer is C) Flashing. A special mark (yellow buoy), if lighted, may exhibit a flashing light rhythm. This is in accordance with the U.S. Aids to Navigation System, which specifies that special marks should display a flashing yellow light to distinguish them from other types of navigation lights. The other options are incorrect because: A) Morse "A" is not a standard light rhythm for special marks, B) Equal interval is not a recognized light characteristic for special marks, and D) Occulting lights are not used for special marks.
