Experimental design requires that the change in the dependent variable may be solely attributed to the change in the independent variable, while controlling for any extraneous variables that could influence the results. This is known as a cause-and-effect relationship, where the independent variable is the cause and the dependent variable is the effect. Therefore, option D is the correct choice.
