Answer 2

A. The parasympathetic system counteracts the sympathetic system.

Step-by-step explanation:

Homeostasis refers to the tendency of organisms to maintain the steady state, that is, to maintain the constant internal environment. The parasympathetic division of autonomous nervous system serves to control the internal organs of body and maintains the resting state by conservation or restoration of energy. The sympathetic division serves to mobilize the energy during emergency conditions and prepares the body for fight and flight conditions. Hence, antagonistic effects of these two divisions maintain an internal body balance.
