Answer:
Conscientiousness
Explanation:
Conscientiousness is the trait of the big five-factor model proposed by Costa and McCrae. This is the trait in which if a person gets a high score means he/she is organized, disciplined and hard-working. He/she is goal-directed and very keen on norm and regulation.
Thus Conscientiousness is the most reliable, stable, organized and well-disciplined trait in a person. It is the growth of self-regulation and management.
