Final Answer : A, Explanation :  The control group in this experiment is the group that does not receive the treatment being tested. In this case, the treatment being tested is the presence or absence of money in the tip jar. The patrons who see an empty tip jar are the control group because they do not receive the treatment of having money in the jar. The other groups (those who see money in the jar and those who leave a tip) are the experimental groups.
