Solution
The correct option is A Spongocoel (paragastric cavity)
- A spongocoel can be defined as the large, central cavity of sponges. Water enters the spongocoel through hundreds of tiny pores called as ostia and exits through the larger opening (osculum). It is also known as a paragastric cavity.
- Coelenteron: the digestive cavity of coelenterates. It has a single opening into which all food is taken and through which all waste products are ejected.
- The pseudocoelom is a fluid-filled body cavity lying inside the external body wall of the nematode that bathes the internal organs, including the alimentary system and the reproductive system.
- Schizocoelom: Body cavity formed by the splitting of mesoderm.
Hence the correct option is B.
