One of the Big Five traits, characterized by warmth, gregariousness, assertiveness, activity, and excitement seeking.

• A. Neuroticism
• B. Openness
• C. Extroversion
• D. Agreeableness

Answer: (C)

Extroversion is the Big Five trait that captures sociability and energy. The facets described—warmth, gregariousness, assertiveness, activity, and excitement seeking—map directly onto this dimension. Warmth reflects friendliness, gregariousness is enjoying other people’s company, assertiveness involves taking charge in social settings, activity signals high energy and a quick pace, and excitement seeking indicates a preference for stimulating experiences. People high in extroversion typically draw energy from social interaction and seek out social and exciting activities, while those lower in extroversion (introverts) may prefer quieter, less stimulating environments. The other traits describe different patterns: neuroticism relates to emotional stability, openness to experience to imagination and novelty, and agreeableness to cooperativeness and trust (though warmth is considered a facet of extroversion in this framework, not a defining feature of agreeableness).
