An experiment should have only one independent variable.
The answer is A, obesity.
Fun fact: the United States has the highest obesity rate out of any country in the world. This might be due to the fact that the average citizen gets zero exercise and loves fast food.
D.........................
The answer to this question is B) <span>Handling stress effectively involves recognizing what your stressors are, developing healthy behaviors to minimize stress, and adopting positive coping skills. This is because of the following reasons:
It can't be A) because attempting to ignore the thing that is stressing you will likely cause even more stress. Especially due to the fact that it may be impossible to ignore (i.e. your boss annoys you)
C) would not work because seeing a therapist may cause more irritation and stress, whether due to the large amounts of money needed to pay for the therapist, you may just hate therapy, etc.
D) isn't a good option because "doing whatever it takes" ranges across a LOT of inappropriate options that I shouldn't list. It may also lead to more textually appropriate, but still negative reactions, such as punching the stressor. This is a bad idea in almost every case.
For these reasons, B) is the best option. Hope I was the brainliest! And I hope this helps! :)
