Hope it helps.

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

Explanation:

The sympathetic and parasympathetic divisions are part of the autonomic nervous system and work antagonistically to each other.  

The sympathetic nervous system is the one that prepares the body for "fight or flight" under emergency or stress conditions. On the other hand, the parasympathetic nervous system is related to the resting phase of the body.  

The general effect of the sympathetic nervous system is to mobilize the energy while the parasympathetic nervous system serves to restore the energy level of the body.
