Vedclass · Answer

(A) The phylum $Porifera$ (sponges) is characterized by the presence of a water transport or canal system. In these animals,the sexes are not separate (hermaphrodite),meaning eggs and sperm are produced by the same individual. Fertilization is internal,and development is indirect having a larval stage which is morphologically distinct from the adult. Therefore,the correct option is $A$.

In the animals of this phylum,the formation of gametes and internal fertilization are observed.
