In small angle stability theory, the metacenter is located at the intersection of the inclined vertical centerline and a vertical line through __________.

Correct Answer: Option D — B

Small angle stability theory defines the metacenter as the limiting intersection point of the line of action of the buoyant force with the centerline as the angle of heel approaches zero. The buoyant force acts vertically upward through the center of buoyancy (B) as the hull inclines.
