The control group in an experiment is the group that does not receive the experimental treatment. In this case, the treatment is alcohol, so the control group should receive drink Z, which contains only orange juice and no alcohol. This allows researchers to compare the effects of alcohol on appetite by comparing groups that received alcohol (drinks X and Y) with the group that did not (drink Z).
