Answer
(a) The buoyant force is same in each case as the weight of the body is same in each case and the buoyant force is equal to the weight of the liquid displaced by the immersed part of the body which balances the weight of the body.
(b) Liquid A has the least density as the maximum part of the body is immersed in liquid A.
(c) Liquid C has the highest density as the body immerses the least in liquid C.
