Step-by-step explanation:
The correct answer regarding Gordon Allport's trait categories is C - They represent three levels of traits: cardinal, central, and secondary.
Allport's theory categorized traits into cardinal traits, which are dominant and define a person's overall personality; central traits, which are general characteristics forming the foundation of personality; and secondary traits, which are less apparent and not as consistent, often only present under specific circumstances or in certain behaviors.
It is important to note that these categories are not exclusively based on genetic factors, nor do they include only observable behaviors; they are not focused solely on situational influences, nor are they claimed to be universally applicable across cultures.
The correct option is C.
