Answer:
B. conscientiousness
Explanation:
The Big Five or Model of the Five Great Factors was born from studies on the Theory of Personality Traits, representing a conceptual and empirical advance in this area, as it described basic human dimensions in a consistent and replicable manner. The five great personalities are: neuroticism, extroversion, openness to new experiences, sympathy and conscientiousness. A longitudinal study of more than 1,200 individuals over seven decades revealed that a higher consciousness factor score of the five major personalities predicted a lower risk of early childhood death by late adulthood.
The conscientiousness factor measures the degree of concentration. Those with high scores are highly motivated, disciplined, committed and reliable. Those with poor results are undisciplined and easily distracted.
