Answer:
E. do not always behave rationally because they are overly optimistic about their future behavior. 
Explanation:
Behavioral economics is the study of irrational economic decisions from people's behavior. 
Behavioral economics includes the people's emotional framework to make choices beyond the rational choice theory, which states that a rational person is not moved by emotions and social factors to choose the option that maximizes their satisfaction.
To be overly optimistic about your future behavior is biased from social factors and it is a behavior that could be understood from the human emotional framework.
