The centre of buoyancy of a floating object is :
W
(A) At the centre of gravity of the object.
(B) At the centre of gravity of the submerged part of the object.
(C) At the centre of gravity of the remaining part outside the fluid of thè object.
(D) At the centre of gravity of the fluid displaced by the submerged part of the object.
