The dependent variable is the variable that is being measured or observed to determine whether it changes in response to the independent variable, which is the variable that is being manipulated in the experiment. The experimental group refers to the group that is being tested or experimented on, while a sample refers to a subset of the population being studied. Therefore, A) dependent variable is the best choice as it directly answers the question.
