I would ask for feedback and ask if you can revise and have her re-grade. (You won’t get that grade, but you’ll learn how to write an A paper!) That will also show that you can choose a topic she doesn’t like and present it well. She will she you want to learn and that this isn’t grade grubbing.
At the end of the year, you should hope to get a 4 or 5 on your AP exam. That would be great! An A and a 2 is a sham…
