Final Answer :
C
Explanation :
The control group in an experiment is the group that is not exposed to the experimental treatment or condition. In this case, the experimental treatment is the stress-inducing condition of solving a difficult math problem in front of a group of math professors. Therefore, the control group would be the participants who were not subjected to this stress-inducing condition, meaning those who performed the easy math task. Since the question does not specify whether the control group should be dieters or non-dieters, and considering that Arash's experiment is designed to examine the relationship between stress and eating while on a diet, both dieters and non-dieters are included in the experimental design. However, the correct identification of the control group is based on the task difficulty, not the dieting status. Thus, the control group includes the participants (both dieters and non-dieters) who performed the easy math task.
