The process of flipping a coin to determine group assignment is called randomization. This helps to ensure that the two groups are similar in terms of any potential confounding variables that could influence the results. Establishing a control group and establishing controls are important steps in experimental design, but do not specifically refer to the process of group assignment. Random sampling refers to the process of selecting participants from a larger population, and is not relevant in this scenario since the researcher already has a pool of potential participants. Therefore, the correct answer is B) randomization.
