Buoys are marked with reflective material to assist in their detection by searchlight. Which statement is TRUE?

Correct Answer: Option C — A preferred-channel buoy displays either red or green reflective material to agree with the top band of color.

Preferred-channel buoys are horizontally banded. To assist in identification at night, the reflective material matches the color of the top band. If the top band is red, the reflective material is red; if green, the reflective material is green, as specified in the U.S. Aids to Navigation System.
