The correct option is A Choanocytes in all
Sponges have a water transport or canal system. Water enters through minute pores (ostia) in the body wall into a central cavity, spongocoel, from where it goes out through the osculum. Choanocytes or collar cells line the spongocoel and the canal. They can reproduce both sexually and asexually. Sponges are omnivores. Phylum Coelenterates include members with coelenteron while sponges belong to phylum Porifera. So, the correct option is 'Choanocytes in all'.
