Teacher Gives Student Who Did All Work Lowest Grade

So I (16F) am in a group project class. we were in groups of 3, and I was paired with Lana (16F) and Ian (16M). we had a week to make a presentation. I did the research, wrote most of the scripts, and put together the slides. lana showed up once and gave me few printed pictures for a presentation, that’s the only time she “helped” then she spent the rest of the week not doing anything, ian helped a bit, but not much. we all presented and the teacher said we all did a good job, then she graded us. (We use different grade system) lana got 10/10 ian got 9/10 and I got a 7/10
I got upset and asked the teacher the reason she gave me the lowest grade, all she said was that lana was “more confident” during the presentation and ian “helped with the visuals” I said that I did 90% of the work and that it wasn’t fair, she then said that grades are based on presentation, not effort, The teacher looked annoyed and said she graded fairly and I shouldn’t be upset with her grading based on how active we were during a presentation, Now my teacher is telling my parents that I was rude and disrespectful and that I’m acting like I’m entitled. Lana said I was being “too much” and I “should’ve just asked nicely” I feel like I’m not the problem. If I worked the hardest i should’ve gotten the grade I deserved.
AITA?
