Final answer:
Adaptability is not one of the Five Big Personality traits identified by Costa and McCrae; the Big Five traits are Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.
Step-by-step explanation:
The Five Big Personality traits identified by Costa and McCrae are Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Among the options given, the one that is NOT one of the five big personality traits identified by Costa and McCrae is C. Adaptability. This factor is not considered one of the core components of the Five Factor Model. The Big Five are often remembered using the mnemonic OCEAN, with each letter standing for one of the traits. Although adaptability might be related to some of the Big Five traits indirectly, it is not one of the core traits in this model.
