Which two dimensions of personality have the eysencks emphasized?

Extraversion-introversion and emotional stability-instability

Hans Eysenck (1916-1997) was the one who received more acclaim for his work in the field of psychology, but his wife Sybil (now his widow) is a personality psychologist also and collaborated much with her husband.  

The terms extraversion and introversion were first popularized by Carl Jung. However, Hans Eysenck did much further development of the extraversion-introversion scale in terms of how individuals interact with other people.

The Eysenck Personality Questionnaire also includes emotional stability-instability as another key factor in personality.   The questionnaire yields results that classify persons as either stable introverts, unstable introverts, stable extraverts, or unstable extraverts.

The answer is    "illustrate why one's dreams need to be pursued in a logical order if success is to be obtained"  so c is the answer. : )
