Hans eysenck claimed all of the following except
a. personality is influenced by one's genetic predisposition
b. personality is influenced by conditioned behaviors
c. neuroticism is a basic trait that influences behavior
d. personality is influenced by biological factors

The answer is

C. neuroticism is a basic trait that influences behavior

The correct answer is option C, neuroticism is a basic trait that influences behavior

Eysenck's theory of personality is based on three logical attributes namely:  

a) introversion vs. extroversion – Extroversion leads to sociable life , while introversion causes need of being alone and limited interactions

b) neuroticism vs. stability – Neuroticism leads to anxiousness and overactive sympathetic nervous system while  stability leads to emotional stability

c) psychoticism vs. socialization. - psychoticism  leads to independent thinking, and hostility. While socialization leads to co-operative and conventional behaviour.  

Thus , according to Eysenck's theory only neuroticism is not only a basic trait that influences behavior
