Answer:
B. Hydrostatic skeletons
Explanation:
A hydrostatic skeleton is a fluid-filled skeleton that is present in many invertebrates that have soft bodies. Some of the jelly fishes are among them. The hydrostatic skeleton of jelly fishes can be compressed as it is filled with fluid.
However, it can regain the original shape once the pressure is removed. The ability of hydrostatic skeleton to be compressed and to regain the original shape help these jellyfishes to resist deformation of the body.
