Answer:
D. Who are the main characters?
Step-by-step explanation:
Literal questions are questions that have answers that are directly stated in the text. If you read a story, the main characters are directly stated because you follow them throughout the story. The other answers, A, B, and C, are evaluative questions. The answers to these questions are based off of your opinion. "How do you think the character felt? What do you predict will happen next? When would you use this information?" These are all based off of what you think, not what is stated in the story.
