70% to pass

Lighted white and orange buoys must show which color light?

A Orange
B White
C Alternating yellow and white
D Red
AI Explanation

The correct answer is B) White. Lighted white and orange buoys must show a white light. This is in accordance with the United States Aids to Navigation System, which specifies that lighted buoys marking the main channels and fairways must display a white light. The other answer choices are incorrect because orange buoys do not display a colored light, alternating yellow and white is for unlighted buoys, and red lights are used for port side markers, not white and orange buoys.
