Answer: A. Direct democracy.
Explanation:
Direct democracy is the purest type of democracy that exists, in it, everyone has a voice and vote on every political decision that will be made. It was common in ancient Greece where all men had the right to vote on the decisions to be made.
This type of democracy is common in small groups, for example when electing the president of a classroom, as everyone has the opportunity to give their opinion and select the person who will be the president.

After the surprising finding, the researcher decides to conduct the same study in her lab which is an example of experimental research.
Experimental research is research that involves two sets of variables. One of the sets of the variable is constant which is further used to determine the difference with the second set of variables.
Experimental research is based on a scientific research design that tests a hypothesis by experimentation. It uses one or more independent variables on one or more dependent variables.
Experimental research is conducted over time in a controlled environment. In the question, the researcher is conducting the research in her lab which is a controlled environment. It is also given in the question that the study she has heard about was conducted in a month.
