Answer:
a. stress
Explanation:
Stress is a natural process of the body, which occurs when a person is in a situation of discomfort, or danger. In this case, stress is a stimulus that signals the body to initiate a defense or escape reaction, in relation to the uncomfortable situation that is happening.
When we get stressed our body releases adrenaline, cortisol and
norepinephrine, which prepares us for a possible fight.
It is important to note that despite being a natural response of the organism, excess stress can cause many disorders to the organism, whether on a physical and biological level, or, socially.
