Answer:
The correct answer is option c. the sympathetic and parasympathetic nervous systems.
Explanation:
The parasympathetic nervous system is the one that controls involuntary functions and acts. It also causes or maintains a body state of rest or relaxation after an effort or to perform important functions such as digestion.
The sympathetic nervous system is the one that controls visceral reactions and reflexes, that is, it controls how our body responds to a threatening situation, as is the case in the example.
Both systems make up the autonomic nervous system which is in charge of controlling the involuntary functions of our body.
