The independent variable is the variable that is being manipulated or changed in the study, in this case, it is the consumption of sweets before bedtime. The dependent variable is the variable being measured, in this case, it is the level of activity in the children after eating sweets. The control condition is a group that is used as a comparison to the experimental group to ensure that the effects observed are due to the manipulation of the independent variable. A placebo is a substance or treatment that has no therapeutic effect and is used as a control in experimental studies. Since the option A fits the definition of an independent variable, it is the correct answer.
