Final Answer :
B
Explanation :
A nerve net is found in cnidarians, such as jellyfish and coral, and consists of a diffuse network of neurons that controls primitive sensory and motor functions. Flatworms also have a nerve net, but they also have a more centralized nervous system. Annelids (segmented worms) and arthropods (such as insects and crustaceans) have a ventral nerve cord and a brain, while sponges lack a nervous system altogether.
