According to the two-factor theory of motivation, all of the following are sources of job satisfaction EXCEPT:

A) sense of responsibility.
B) opportunity for advancement.
C) feeling of personal growth.
D) working conditions.
E) sense of achievement.

The two-factor theory of motivation, also known as Herzberg's motivation-hygiene theory, suggests that job satisfaction and dissatisfaction arise from two different sets of factors. Factors leading to job satisfaction are called motivators and include sense of responsibility, opportunity for advancement, feeling of personal growth, and sense of achievement. Working conditions are considered a hygiene factor, which does not lead to job satisfaction but can cause dissatisfaction if not adequate.
