______ is a consistent and enduring characteristic of personality.

A) Excitement
B) Fear
C) Boredom
D) Temperament

Temperament refers to basic, innate, and stable patterns of behavior and response that are present from infancy and throughout a person's life. It is considered a consistent and enduring characteristic of personality. Excitement, fear, and boredom are emotional states that can vary greatly depending on the situation and context, and therefore are not considered consistently enduring characteristics of personality.
