A) internal locus of control
B) growth need strength
C) extroversion

Growth need strength refers to an individual's desire for personal growth and development, and people with high growth need strength tend to be more motivated by challenging and meaningful work. Therefore, the relationship between challenging job characteristics and job satisfaction should be higher among employees with a high level of growth need strength. Internal locus of control, extroversion, and education do not necessarily relate to an individual's motivation or desire for challenging work.
