McCrae and Costa's five personality factors

A) are the first five factors identified by Cattell.
B) show that environment is more important than heredity.
C) include agreeableness and conscientiousness.
D) include sociability, impulsivity, and emotionality.

McCrae and Costa's five personality factors are Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (also known as Emotional Stability). Two of the factors listed in option D, sociability and impulsivity, would fall under Extraversion, while emotionality would fall under Neuroticism. Option A is incorrect because Cattell identified 16 personality factors, not five. Option B is also incorrect as both heredity and environment play a role in shaping personality, and there is no evidence from McCrae and Costa's work to suggest that environment is more important than heredity.
