Explanation:

A dependent variable is what is measured in an experiment. In this bar - graph, the average level of happiness is being measured based on how often candy is eaten. The variable "how often do you eat candy" is the independent variable (it is manipulated or changed), and the average level of happiness depends on it. Options A (type of candy) and B (if candy is given as a reward) are not even variables in the context of this graph. Option C (how often do you eat candy) is the independent variable.

Answer:

D. average level of happiness
