Detailed explanation-1: -Amoeba-like cells found throughout the sponge are called as amoebocytes. They store, digest and transport food, excrete wastes and secrete skeleton and also may give rise to buds in asexual reproduction. Thus, the correct answer is option C.

Detailed explanation-2: -Amoebocytes function in regeneration and in transportation of food particles acquired at the choanocytes throughout the body of the sponge.

Detailed explanation-3: -An amebocyte or amoebocyte (/əˈmiː. bə. saɪt/) is a mobile cell (moving like an amoeba) in the body of invertebrates including cnidaria, echinoderms, molluscs, tunicates, sponges and some chelicerates. They move by pseudopodia.

Detailed explanation-4: -Collar cells have whiplike structures that beat back and forth to move water through the sponge. Collar cells also strain food from the water. The collar cells act as the sponge’s digestive system. The soft bodies of most sponges are supported by a network of spikes.
