C. attitude about the subject of the story.

The tone of a narrative or story is best defined as the attitude that an author has towards the subject, or the audience, of a story. Tone is usually conveyed by the author's choice of words. If the author chooses cheerful words, we know that the tone of the story is a happy one. On the other hand, if an author uses sad words, then the tone of the story is a sad one as well. The tone influences the feelings that the reader has when reading the text as well.
