Gordon Allport, a significant figure in modern trait theory, outlined three personality traits in 1936:
- Central Traits: These define the fundamental characteristics of personality, representing core aspects of character that form an individual's personality structure.
- Cardinal Traits: These are overarching characteristics that predominantly shape an individual's behavior. A person with a cardinal trait is largely identified by this single, defining characteristic.
- Secondary Traits: These are situational characteristics that manifest only under specific circumstances, being less prominent than central traits.
Following Allport's classification, the correct identification comprises Central traits, Cardinal traits, and Secondary traits, designated as (A), (C), and (E).
