Detailed explanation-4: -Spongocoel is the sponges’ large, central cavity. Via hundreds of tiny openings, water enters the spongocoel (Ostia) and exits through the larger opening (osculum). It is a paragastric cavity and has epithelial cells lining it. A spongocoel is a large, central sponge cavity.

Detailed explanation-5: -The correct option is C Spongocoel.
