D. The sympathetic system prepares the body for stress and activity and the parasympathetic system prepares the body for rest.

Explanation:

Sympathetic and Parasympathetic nervous system are two divisions of autonomic nervous system. Acetylcholine is a common neurotransmitter released by preganglionic neurons of both systems. The post Ganglionic neurons of these two systems release different neurotransmitter. The sympathetic nervous system is concerned with 'fight and flight response' The parasympathetic nervous system is concerned with 'rest and digest ' response.
