Q. Choose the correctly matched characters of the phylum
A) Ctenophore – Radial symmetry – Cellular level of organisation – Acoelomate
B) Platyhelminthes – Bilateral symmetry – Organ and organ system level of organisation – Pseudocoelomate
C) Echinodermata – Radial symmetry – Organ system level of organisation – Coelomate
D) Coelenterata – Bilateral symmetry tissue level organisation – acoelomate
Explanation
Ctenophora have radial symmetry with tissue level of organisation, acoelomate animals. Platyhelminthes have bilateral symmetry with organ and organ-system level of organisation but are also acoelomate animals. Characters of echinoderms are true. Coelentrata have bilateral symmetry with tissue level organisation acoelomate animals
