The rats that received the placebo are serving as the control group in this experiment. The control group is the group that does not receive the intervention (vitamin C in this case) and is used as a comparison to the experimental group. The control group provides a baseline for comparison and helps to determine if the intervention (vitamin C) had an effect on the outcome (incidence of common cold).
