In a study, the independent variable is the variable that is manipulated or changed by the researcher to observe its effect on the dependent variable. In this scenario, the independent variable is the type of music (waltzes vs. military marches), which is being controlled by the psychologist. On the other hand, the dependent variable is the variable that is being observed and is expected to change in response to the independent variable. In this case, the dependent variable is the participant's mood, which is being measured with a paper-and-pencil test. Therefore, the correct answer is B.
