Solution

The correct option is B Both
The law of floatation can be stated as the weight of a floating body is equal to the weight of the liquid displaced.The centre of gravity of a floating body and the centre of buoyancy are in the same vertical line.When a body floats with its volume partially above the liquid surface, the volume of the liquid displaced by the body is equal to the volume of the submerged portion of the body. Since the body is in equilibrium, the force of buoyancy acting on the body must be equal to its weight. This is known as the law of floatation.
