Solution
The correct option is A Having intercellular digestion
Sponges or porifera, because of certain unique features of their organisation they are usually regarded as a separate sidebranch from the Metazoa, the Parazoa. They have neither the true tissues nor organs characteristic of the metazoans and their cells retain a considerable degree of independence. However, unlike the Protozoa the various kinds of cells do not act entirely as individuals but show a definite social organisation with individual cells specialised for the functions of feeding, support or reproduction. Food particles are ingested by the choanocytes and digested intracellularly, as in free-living protozoans.
