Answer:
A. and E.
Explanation:
From the available options, the only two that would be considered as individual behaviors would be
A. eating a large bowl of chocolate ice cream right before getting into bed
E. watching a movie on a tablet while in bed, just prior to bedtime
Both of these are choices being made by the individual willingly, and both can affect the length and quality of sleep that they can have. The other options listed are usually either necessary or depend on other external factors such as environmental or social which are out of the control of the individual in question.
