Correct answer: to provide electrical signals to initiate peristalsis.
Brief explanation: the nervous system (especially the enteric nervous system, with input from the autonomic nerves like the vagus) generates and coordinates the electrical activity that causes smooth muscle contractions (peristalsis) and modulates secretions and blood flow in the GI tract. It does not produce digestive enzymes (those come from saliva, stomach, pancreas, etc.), nor does it carry nutrients or provide oxygen (those are the roles of the circulatory/lymphatic and respiratory systems, respectively).
