Answer:
The revision that best uses direct characterization is:
A. Millicent's tense posture evaporated, replaced by a genuine smile.
Step-by-step explanation:
Indirect characterization happens by inference, so to speak. Through the character's actions or speech, we get to infer what that person is like or how she feels and thinks. Direct characterization, on the other hand, relies on the author's description of the character. It is the narrator telling us what that person is like - her desires, her passions, her physical appearance, her emotional state and so on. That is why, among the options provided, the one that best uses direct characterization is letter A. It is the author describing Millicent's posture. The other options show Millicent's actions, thoughts, and words.
