(D) The water canal system (or water transport system) is a characteristic feature of the phylum $Porifera$. Water enters through minute pores called $ostia$ into a central cavity called $spongocoel$ and goes out through the $osculum$. This pathway of water transport is helpful in: $1$. Food gathering: Food particles are filtered from the water. $2$. Respiratory gas exchange: Oxygen is taken in and carbon dioxide is released. $3$.
