a

Explanation:

The parasympathetic nervous system is often referred to as the "rest and digest" system. Its main role is to slow down the body's processes, which helps in calming the body and conserving energy. For example, it slows the heart rate, promotes digestion, and relaxes various muscles. Option B is more of a general function of the overall nervous system and homeostasis mechanisms (not specific to parasympathetic). Option C is the function of the sympathetic nervous system (the "fight - or - flight" system). Option D is not a function associated with the parasympathetic nervous system.

Answer:

A. It calms the body and conserves energy.
