Solution
The correct option is D Cnidaria
Members of phylum cnidaria or Coelenterata are diploblastic, aquatic animals with tissue grade of organization, Body contains a large cavity called coelenteron or gastrovascular cavity. Coelenteron has a single opening for ingestion and egestion.Some general characteristics of Cnidaria are as follows. 1) Radially Symmetrical. 2) Body multicellular, few tissues, some organelles. 3) Body contains an internal cavity and a mouth. 4) Two different forms exist, medusa and polyp.5 )Reproduction is asexual or sexual. 6) Has a simple net like nervous system. 7) Has a distinct larval stage which is planktonic. 8) Lives in aquatic environments, mostly marine. 9) Mostly carnivorous otherwise filter feeders. 10) May have a minimal skeleton of chiton or calcium carbonate.
