Answer:
C. To reinforce a theme.
Step-by-step explanation:
Fiction writers may return to certain details or scenes again and again to reinforce a theme, which is the underlying message or central idea of the story. By repeating certain elements, such as a particular object, image, or setting, a writer can emphasize their importance to the story's underlying message, making it more memorable and impactful. Repeating certain details can also help to create a sense of cohesion and coherence within a story, and enhance the reader's understanding and engagement with the story.
