Answer:
d) A group that does not drink soda (caffeinated or decaffeinated) or other caffeinated beverages for 10 days
Explanation:
In an experiment, two groups exist as follows: experimental group and control group. Experimental group is the group that receives the experimental treatment (independent variable) while the CONTROL GROUP is the group that does not receive the experimental treatment.
In this experiment, the experimental treatment is the CAFFEINATED SODA (contains caffeine). Hence, the appropriate control group for this experiment will be the group that does not drink any soda (whether caffeinated or decaffeinated) or other caffeinated beverages for 10 days.
