The correct answer is 1. Emotional stability. Neuroticism and emotional stability are two opposite traits in the Five-Factor Model of personality. Neuroticism refers to the tendency to experience negative emotions such as anxiety, depression, and moodiness, while emotional stability refers to the opposite - the tendency to remain calm, resilient, and in control of emotions. Extraversion, on the other hand, refers to the degree to which a person is outgoing, energetic, and seeks social stimulation, which is a separate trait from neuroticism.
