Solution
The correct option is C Gemmule
Sponges belong to the phylum Porifera. They reproduce by sexual and asexual mode. The asexual mode involves budding. In this process, a new organism develops from an outgrowth or bud due to cell division at one particular site of the parent body. In sponges, a part of parent body produces internal buds known as gemmule which separates from the parent body and forms a new organism. The gemmules are formed in the mesoglea layer of the body wall.So, the correct answer is option B.
