Select the correct matching of animals, their symmetry, organisation and coelom type.A. `{:("Animals","Symmetry","Organisation","Coelom type"),("Ctenophores","Radial","Diploblastic","Pseudocoelomates"):}`B. `{:("Animals","Symmetry","Organisation","Coelom type"),("Echinoderms","Bilateral","Triploblastic","Coelomates"):}`C. `{:("Animals","Symmetry","Organisation","Coelom type"),("Platyhelminthes","Bilateral","Triploblastic","Acoelomates"):}`D. `{:("Animals","Symmetry","Organisation","Coelom type"),("Annelids","Biradial","Diploblastic","Coelomates"):}` |
|
Answer» Correct Answer - C Platyhelminthes are triploblastic, acoelomate organisms showing bilateral symmetry. Ctenophores have radial symmetry, are acoelomates having diploblastic organisation. In echinoderms, larvae have bilateral symmetery while adults have bilateral symmetry while adults have radial symmetery. They are coelomates with triploblastic organisation.
