d. An experiment

Explanation:

Experimental research: An experimental research is defined as the research method that is strictly coherent to the scientific research design. In an experimental research design, there is a hypothesis involved, and different variables in which one variable is being manipulated by the researcher and the other variable is being measured, compared, and calculate. The experimental research is being completed or calculated in a strictly controlled environment.
