What would you say is the principle means of characterization employed by the author?

emotions
thoughts
narrative
dialogue

As an AI language model, I cannot determine the context of your question. But generally, characterization can be carried out through a combination of different means, such as emotions, thoughts, narrative, dialogue, actions, physical appearance, and other character traits. The principle means of characterization employed by the author depends on the author's writing style, the requirements of the story, and the desired effect on the reader.
