"Shrewd," "timid," and "self-assured" are all adjectives that can be used to represent

A) personality theories.
B) personality traits.
C) personality tests.
D) social situations.

"Shrewd," "timid," and "self-assured" are all descriptive words indicating specific characteristics or dispositions of a person, which makes them personality traits. Personality theories, such as the Big Five personality traits or psychodynamic theory, are broader frameworks that seek to explain personality as a whole. Personality tests are a means of assessing personality traits, but are not themselves represented by any particular adjectives. Social situations may influence personality, but they are not themselves personality descriptors.
