In the Context of Implicit Personality Theories, a Central Trait

In the context of implicit personality theories, a central trait like "warm" and "cold" is:

A) whatever the person implicitly believes is the most important aspect of their personality.
B) the best predictor of the person's behavior across a variety of situations.
C) a trait that dominates other people's impression of a person, and to which they mold their understanding of the person's other, non-central traits.
D) only registered non-consciously by other individuals with whom the person interacts.
