Final Answer :
C
Explanation :
A true experiment involves the manipulation of an independent variable to observe the effect on a dependent variable. Therefore, the correct answer is C where the dependent variable is being assessed and is affected by a change in the independent variable. The extraneous variable is controlled for in the research design, so it is not the main focus of the experiment.
