I would most likely chose B. Person vs self. Even though it doesn't say it in this part it talks about Della and how she hopes Jim will like the present then she starts to feel doubt come over her.
" If you don’t do that – if you quit on school – you’re not just quitting on yourself, you’re quitting on your country."
"You’ll need the knowledge and problem-solving skills you learn in
science and math to cure diseases like cancer and AIDS, and to develop
new energy technologies and protect our environment"
all I got.
I think it is B hope you get it right Good luck!
