Interesting situation

[devdog69]

I saw this play last Sunday in a women's college game and it brought up some interesting conversations during our pregame at my sub-state games this past weekend. It happened in a game between SW Mo. State, I'll call them A, and Indiana State, B.

Sitch-Player A drives towards the basket and towards B1, who is in very obvious legal guarding postion and ready to take a charge. A1 leaves her feet and is about to pick up a charging foul when, just before she creams B1, B2 hacks her hard on the arm. The bucket goes in. A1 continues on and rams into B1. What is the call? I'll let some discussion go, before I give their answer.
