The correct option is C.
Buoyancy is an upward force exerted by a fluid on an immersed object, opposing the object’s weight.
Archimedes’ principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This force acts vertically upwards through the centroid of the displaced fluid volume. Buoyancy is a force, not a pressure, and its direction is always opposite to the direction of gravity on the fluid (hence, upward in the case of earth’s gravity).
