Solution
The correct option is D Sponges
Under adverse conditions, sponges disintegrate leaving behind a small ball-like rounded structure called reduction bodies. These reduction bodies contain amoebocytes which are further covered by pinacoderm and spicules. When the conditions become favourable, each reduction body develops into a new sponge.
Hence, reduction bodies are perennating reproductive bodies of sponges.
