The correct answer is A) true.
It is true that Eustress, the type of stress that occurs as a response to positive events, differs from distress in that frequent eustress does not place one at risk for stress-related illness.
The human body responds to stimuli or changes from the exterior. That is basically what the body produces against them: stress. The negative form of stress is distress. The positive form is Eustress, which can be the product of excitement, the accomplishment of something of value, a long period of focusing on something important.
Distress, on the other hand, is the by-product of fear, anxiety, worry, and work pressure.
