Final Answer :
A
Explanation :
The dependent variable is the variable being observed for any possible effects, which is the purpose of the experiment. The independent variable is the variable being manipulated by the researcher, and the control variable is a variable that is kept constant to minimize potential interference with the dependent variable. The hypothetical variable is not a commonly used term in scientific research.
