The dependent variable is the variable that is being measured or observed in the study. In this case, the experimenter is testing whether physical exercise improves people's mood, and the measure of mood, i.e., how happy the subjects are, is the dependent variable. Choosing A or B would be incorrect as the hypothesis and day of the week are not being measured or observed. Choosing C would be partially correct as exercise is an independent variable that is being manipulated, but it is not the dependent variable being measured.
