Verified by Toppr

The correct option is C Nerve-net system
Nerve net is a diffuse network of nerve cells that serves to connect the sensory cells in the body wall to contractile and gland cells. These sensory cells receive impulses and stimuli while nerve cells conduct impulses in all directions and help hydra (cnidarians) to respond. This is the simplest form of the nervous system which is observed in the cnidarians.
Thus, the correct answer is option C.
