The answer is: We imagine how other judge us.
In 1902, Charles Horton Cooley conceived the looking-glass self theory, which suggests that an individual's self develops through other people's perceptions and social communication. Therefore, external judgement establishes a person's self or character.
The rest of the alternatives are incorrect because they do not deal with the psychological concept of the looking-glass self theory: it does not specifically involve assumptions about college or feelings towards our parents.
