According to Hans Selye, stress is
a) a specific response to a specific demand on the body.
b) a cognitive, not physical, response to a threatening situation.
c) any reaction that increases activity in the parasympathetic nervous system.
d) a nonspecific response of the body to any demand made upon it
b is my answer
I don't agree.
According to Hans Selye, stress is not answer b) - a cognitive, not physical, response to a threatening situation.
According to Selye's general adaptation syndrome, stress is defined as answer d) - a nonspecific response of the body to any demand made upon it.
If you want to confirm this answer, you can refer to Hans Selye's work, specifically his book called "The Stress of Life." In his book, he describes stress as a nonspecific bodily response to any demand, whether it is physical, mental, or emotional. This response involves a series of physiological changes that occur in the body to help cope with the demand placed upon it.
