Answer: B - A system of motor nuerons that innervates al muscle cells

Explanation: Autonomic Nervous System regulates body functions for involuntary movements so that you do not have to think about breathing and pumping blood. These actions are involuntary and the autonomic nervous system is there to guide that. Therefore it only acts on smooth and cardiac muscles that are found at the heart, lungs and urinary organs, thus autonomic nervous system does not act on all muscles, making option B the answer.
