In an experimental study, the independent variable is the variable that is being studied to see if it causes a change in the dependent variable. In this case, exercise is being studied to see if it has an effect on stress, so it is the independent variable. The dependent variable is the variable being measured to see if it changes as a result of the independent variable, which in this case would be stress. The control group is a group that is used for comparison and does not receive the independent variable, and the experimental group is the group that does receive it. However, the question only asks about the variable being studied, so the correct answer is B.
