Sponges
Simple aquatic animals with a porous body that water flows through, belonging to the phylum Porifera.
Nerve Fibers
Long, thin extensions from neurons that transmit nerve impulses to other cells.

Final Answer :
C
Explanation :
Amoeboid cells, also known as choanocytes, are responsible for digestion in sponges. Sponges do not have well-developed muscle fibers or nerve fibers, and they are capable of both sexual and asexual reproduction. While separated sponge cells may not survive for long outside of the sponge body, they do not necessarily die immediately.
