submerged body
volume of the floating body
volume of the fluid vertically above the body
displaced volume of the fluid
Answer is Right!
Answer is Wrong!
The correct answer is: D. displaced volume of the fluid.
The buoyant force is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. The buoyant force is equal to the weight of the fluid that is displaced by the object. The line of action of the buoyant force acts through the center of gravity of the displaced fluid.
Option A is incorrect because the buoyant force acts on the displaced volume of the fluid, not the submerged body.
Option B is incorrect because the buoyant force acts on the displaced volume of the fluid, not the volume of the floating body.
Option C is incorrect because the buoyant force acts on the displaced volume of the fluid, not the volume of the fluid vertically above the body.
