Which of the following combinations of phyla and characteristics is incorrect?

  1. Nematodaround worms, pseudocoelomate

  2. Cnidariaradial symmetry, polyp and medusa body forms

  3. Platyhelminthesflatworms, gastrovascular cavity, acoelomate

  4. Poriferagastrovascular cavity, mouth from blastopore


Correct Option: D
Explanation:

The nematodes or roundworms constitute the phylum Nematoda and have a pseudocoelom and complete digestive system. The partial, fluid-filled cavity inside the body of some invertebrates. Cnidarians have two different body plans. Both body plans have radial symmetry. A polyp, such as a hydra, sea anemone, or coral, is shaped something like a vase. Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates and have cavity only one opening to the outside which, in most cnidarians, is surrounded by tentacles for capturing prey. But Porifera does not have a gastrovascular cavity as it does not have specialized tissues and phyla with a true coelom and digestive system. The protostomes include the phyla Mollusca, Annelida, and Arthropoda but not porifera. 

So, the correct option is, 'Porifera gastrovascular cavity, mouth from blastopore'.
