Question 249Navigation General

The correct answer is B) information and regulatory buoys. White lights are commonly found on information and regulatory buoys, which are used to convey auxiliary information to mariners, such as anchorage areas, boat ramps, or special instructions. These buoys do not mark the main navigational channel, so white lights are not found on preferred channel buoys (option A), numbered buoys (option C), or special purpose buoys (option D), which serve different functions in the navigational system.
