The correct answer is option B, that is, the sympathetic system prepares the body for stress and activity and the parasympathetic system prepares the body for rest.
Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system that works obligatorily. The sympathetic nervous system holds the key in controlling the body at the time of stress and injury, it is generally regarded as fight or flight. It contracts the muscles of the heart in order to enhance the rate of the heart.
On the other hand, the parasympathetic nervous system is responsible to monitor the function of the body when it is at rest. It assists in sustaining the homeostasis in the body. It relaxes the muscles of the heart in order to reduce the rate of the heart.

<span>A four-stage process that creates two identical cells from one original cell.
Prophase
This is the first and longest stage, the chromosomes become visible and the centrioles separate, moving to opposite poles.
Metaphase
In the second stage, the chromosomes line up in the cell, becoming connected to the centromere by the spindle fiber.
Anaphase
In the third stage, the sister chromatids separate into two chromosomes, they have been pulled apart.
Telophase
The final stage of mitosis where the chromosomes gather at opposite ends of the cell, losing the distinct shapes. Two new nuclear membranes form around each of the two regions of DNA, spindle fibers are gone.</span>
