According to Hans Eysenck, the three dominant personality traits are not cardinal, central, and secondary traits. The correct answer is "OF." Cardinal, central, and secondary traits are actually a part of Raymond Cattell's 16 Personality Factors model, not Eysenck's theory.
Hans Eysenck focused on three major dimensions of personality which are extraversion, neuroticism, and psychoticism. These dimensions are known as the PEN model. Extraversion refers to the level of sociability, assertiveness, and talkativeness in an individual. Neuroticism relates to emotional stability or instability. Psychoticism deals with aggressiveness, interpersonal hostility, and impulsivity.
Therefore, in the context of the question, the best answer is "OF" because cardinal, central, and secondary traits are associated with Raymond Cattell's model, not Hans Eysenck's theory.
