Triploblastic animals have a third layer, mesoderm which gives rise to muscle and skeletal structures, which surrounds the body cavity. Metamerism is the phenomenon of linear series of body segments which are similar in structure. Metameric animals exhibit bilateral symmetry.
Echinoderms are triploblastic but show radial symmetry.
So, the correct option is C.
