Question 1997 Deck Safety

The correct answer is B) KB. The abbreviation KB represents the height of the center of buoyancy, which is the vertical distance between the center of buoyancy and the keel of the vessel. This is a fundamental concept in naval architecture and ship stability calculations. The other options are incorrect: A) BK is not a standard abbreviation used in this context. C) CB represents the center of buoyancy, not its height. D) BM represents the metacentric height, which is a different stability parameter.
