Stress is a. positive or negative, depending on circumstances b. a body's automatic physical response c. a negative reaction to outside influences d. a and b only

The answer is D. A and B only.

Explanation: I got the answer correct on edge 2020. Stress is both a positive or a negative thing because sometimes you can get stressed over an exciting thing, such as a wedding or a birthday. But other times you can get stressed over work, or too much homework at the end of the day. And B because stress is something normal for the body. If there is a lot to expect coming or a lot to do in general your body will start to freak out in sometimes a good, or sometimes bad way. Thank you. Once again the answer is, D. A and B only.
