Question 2031 Deck Safety

The correct answer is D) at all times. The center of buoyancy and the metacenter are always in the line of action of the buoyant force, regardless of the stability condition (positive, negative, or neutral). This is a fundamental principle of ship stability and is true by definition. The other answer choices are incorrect because the relationship between the center of buoyancy, metacenter, and the line of action of the buoyant force does not depend on the specific stability condition. It remains the same at all times.
