(d) Comb plates present in ctenophores help in digestion. (e) Water vascular system is characteristic of Echinoderms.
Choose the correct answer from the options given below:
(a), (d) and (e) are correct
(b), (c) and (e) are correct
(c), (d) and (e) are correct
(a), (b) and (c) are correct

Statement (b) is correct as Echinoderms are triploblastic and coelomate animals . Statement (c) is correct because Aschelminthes (Roundworms) possess organ-system level of body organisation . Statement (d) is incorrect because the ciliated comb plates in Ctenophores help in locomotion, not digestion . Statement (e) is correct as the water vascular system is a distinctive feature of Echinoderms .
