Solution

The correct option is D Archaeocytes
Freshwater sponges (Spongilla) produce special bodies called as gemmules. During unfavorable conditions, gemmule germinates and produces new sponges. For gemmule formation, archaeocytes laden with food material in the form of glycoprotein or lipoprotein get aggregated into mass. Thus, the correct answer is option D.
