The control group in the experiment is the group that serves as a comparison to the test groups. It does not receive any sweetener in its food. The other three test groups consume different amounts of sweetener in their food.
Test groups:
- Group A: This test group receives 10 mg/day of sweetener in their food.
- Group B: This test group receives 50 mg/day of sweetener in their food.
- Group C: This test group does not receive any sweetener in their food.
- Group D: This test group receives extra food, but no sweetener.
Explanation:
- The purpose of having a control group is to provide a baseline for comparison. By not giving any sweetener to the control group, any changes observed in the test groups can be attributed to the sweetener and not other factors.
- Group A and Group B are the test groups that receive different amounts of sweetener in their food. These groups are used to study the effects of different dosages of sweetener.
- Group C is the control group that does not receive any sweetener. By comparing the results of Group C with the test groups, the researchers can determine the impact of the sweetener on various factors.
- Group D is not a test group related to the sweetener. It receives extra food, but no sweetener. This group may serve as a control group for other factors being studied in the experiment.
In conclusion, the control group in this experiment is the one that does not receive any sweetener in their food (Group C).

The correct answer is option 'C', which states that the control group receives no sweetener. Let's understand why this is the correct answer.
Explanation:
- The control group is a group in an experiment that is used as a standard of comparison. It does not receive the variable being tested, which in this case is the sweetener.
- The purpose of having a control group is to provide a baseline to compare the results of the test groups to. By not introducing the sweetener to the control group, any changes observed in the test groups can be attributed to the sweetener, rather than other factors.
- In this experiment, there are four groups of mice: one control group and three test groups. The test groups consume different amounts of sweetener in their food.
- Option 'A' states that the control group receives 10 mg/day of sweetener. This would not make it a control group because it is being exposed to the variable being tested. The purpose of the control group is to not receive the sweetener at all.
- Option 'B' states that the control group receives 50 mg/day of sweetener. Again, this would not make it a control group as it is being exposed to the variable being tested.
- Option 'D' states that the control group receives extra food. While it is important to have similar conditions for all groups, providing extra food to the control group would not make it a control group. The control group should not receive any additional treatments or variables.
- Therefore, the correct answer is option 'C', which states that the control group receives no sweetener. This ensures that any changes observed in the test groups can be attributed to the sweetener, as the control group provides a baseline for comparison.
