Answer:
D. The third person omniscient point of view means that the audience knows the characters are mostly likely about to have an awkward and disappointing interaction.
Explanation:
First, the passage doesn't use any first-person narration. That crosses out B and C. A is tricky, but no where in the text does it say that Ellie Fitz is the right girl for Edgar. This leaves D, and D makes sense because as you can imagine, Ellie won't be happy to be rejected by Edgar sense she "...had had a secret crush on him since 7th grade."
