Answer:
D. How much should the narrator know about the story?
Step-by-step explanation:
A narrator has direct control over how the reader is able to see a story. For example, a story written in 1st person gives access to a character's inner thoughts and feelings, and we know as much as they know. 3rd person limited acts similarly, but there is a little less intimacy. 3rd person omniscient lets the reader see into everyone's thought, meaning that having access to internal wants seems a little less special because it is that way for multiple characters. This way prevents one main character from standing out more than another.
