The right answer is A.
Metabolic homeostasis is provided by a set of interactions between the central nervous system (CNS) and peripheral tissues. The CNS controls the periphery by regulating the fraction of energy that enters the body (caloric intake) and that which emerges from it.
To perform this role, the CNS receives signals from peripheral organs and provides information on peripheral metabolism, as well as the extent of the reserves available to the body.
