The correct answer is by using the antagonist.
The antagonist is a molecule that blocks a biological response by binding to the receptor. So, you add antagonists to the receptors you want to determine and see which antagonist blocked the response. By blocking the specific response you can get the answer what receptor it was.
A control group is a group that does studies or Experiments that does not receive treatment by researchers and is then used as a benchmark to measure how the other tested subjects do. Ex: Experimenting Arizonas and water together.
