Answer:
The answer is B. Epinephrine.
Explanation:
Epinephrine is also known as adrenaline and is a hormone and a neurotransmitter that increases heart rate, constricts blood vessels, dilates the airways, and participates in the fight or flight reaction of the sympathetic nervous system. Epinephrine is the hormone in situations where we have to be alert and activated, as it predisposes us to react quickly and prepares us to get the most out of our muscles when it is necessary to move with a certain speed. Epinephrine is produced by our body in the adrenal glands that are located above the kidneys.
