Replying to Date Dilemma

Ok this is actually really important and I need help making a decision. I'm graduating and for our Grand March I need to choose a date. I currently have a good friend as my date (girl A) but another good friend of mine (girl B) is graduating with me. They have gotten in a big fight recently so they aren't on speaking terms and all they do is fight and bitch. Anyway, Girl B recently broke up with her boyfriend and so she is planning on possibly taking gild A's ex as her date. They're super good friends but he is not on speaking terms with girl A. Now I have to choose. I can take girl A and have her, B and the guy fight all night. Or, I could take B and cut out girl A but risk her getting angry at me. Lastly, I could take another girl who I'm close with but girl A hates because she was accused of homewrecking girl A's relationship with the previously mentioned guy. However, the other girl and guy are good friends so they'd be chill with everyone and girl A would hate me.

I know that this is confusing but I actually need help.
