Answer:
I'd go with A. and D.
Step-by-step explanation:
The story talks about the relationships between family members, and how they are important to maintain. The narrator describes not being that close with Natalie, but still being eager to help her and spend time with her, demonstrating that Natalie can rely upon her sibling, the narrator.
I also selected D, because all the narrator had to do was be there for their sister, and vice versa. Additionally, the mother had already had popcorn prepared without even words being exchanged, demonstrating love.
