Aunoccupied space below the waterline
Bvolume of intact space above the waterline
Cdifference between buoyancy in salt and fresh waters

AI Explanation
The correct answer is B) volume of intact space above the waterline. Reserve buoyancy refers to the volume of undamaged, watertight space above the waterline that provides additional buoyancy in the event of hull damage or flooding. This reserve allows the vessel to remain afloat and stable even when the overall buoyancy is reduced. The other answer choices do not accurately describe the definition of reserve buoyancy as specified in the U.S. Coast Guard regulations for vessel stability and construction.
