You have been informed that dredging operations may be underway in your vicinity. Which buoy indicates the dredging area?

AI Explanation
The correct answer is B) Yellow buoy. According to the U.S. Coast Guard regulations, a yellow buoy is used to mark dredging or other underwater operations. This type of buoy alerts mariners to the presence of submerged equipment or hazards in the water, allowing them to navigate safely around the dredging area. The other answer choices are incorrect because: A) A white and international orange buoy is used to mark special areas or regulations, not dredging operations. C) A white buoy with a green top is used to mark the safe water between two channels. D) A yellow and black vertically striped buoy is used to mark a wreck or other obstruction, not dredging.
