The sympathetic nervous system controls the response to a threat. We perspire, breathe more quickly and get goosebumps and feel nauseated. The correct answer is c. sympathetic nervous system.
The autonomic nervous system responds to information about the body and the environment by either stimulating or inhibiting bodily functions, typically through the sympathetic or parasympathetic nervous systems.There are two primary divisions of the autonomic nerve system-
- Sympathetic
- Parasympathetic
The sympathetic nervous system controls the "fight-or-flight" reaction, which is activated by danger or stress and can lead to a number of physiological changes. Most blood vessels, including many in the epidermis, digestive tract, and kidneys, constrict when the sympathetic nervous system is stimulated. This happens due to norepinephrine, released by post-ganglionic sympathetic neurons, activating alpha-1 adrenergic receptors. Sympathetic nervous system may impact these organs while under threat or stress:eyes, heart, lungs, digestive tract, liver, and genitalia.

<h3>What are parasites?</h3>
Parasites may be defined as the types of living organism that significantly lives on or in a host organism and gets their food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.
An ectoparasite is a group of parasites that would you choose to study because these parasites live on the external surface of the hosts. So, they are easy to recognize as compared to endoparasites. Some examples of these parasites may include fleas, lice, Nonogenea, Copepoda, etc.
Therefore, among the options given, an ectoparasite is a group of parasites that would you choose to study. Thus, the correct option for this question is A.
