Answer:

c. specialised cells

Explanation:

Sponges are invertebrates that belong to phylum Porifera. Most of them live in marine environment. They do not have true tissues or organs but specialised cells that perform specific functions for example porocytes, amoebocytes, pinacocytes and choanocytes. Porocytes control the water amount entering inside the sponge pores and choanocytes control the water movement inside the sponge body.

Sponges consume food via phagocytosis. They reproduce both asexually and sexually. They are sessile i.e. immobile.
