AI Explanation
The correct answer is A) the center of gravity of the water plane. The center of flotation is the point on the water plane where the downward force of the vessel's weight is concentrated. This is the same as the center of gravity of the water plane, which is the geometric center of the area of the water plane. The other answer choices are incorrect because: B) refers to the center of buoyancy, C) refers to the center of gravity of the vessel, and D) refers to the center of buoyancy.
