Which of the following is a character trait?

• A. Introversion
• B. Loyalty
• C. Cheeriness
• D. Extroversion

Answer: (B)

An enduring quality that guides how someone behaves across different situations is what a character trait is. Loyalty fits this because it describes a steadfast commitment and faithfulness to people, groups, or duties—an attribute that tends to be stable over time and across contexts.

Introversion and extroversion describe a person’s energy preferences and social style, which are more about temperament than a fixed moral quality. Cheeriness describes a mood or outward demeanor rather than a consistent character pattern. So loyalty is the best fit as a character trait.
