Welcome to the world of XD. Since XD has not logic engine, you are going to have create experience for all your combinations. Each home screen would be new art board. I suspect the trouble you have (or will have) is you have your A/B/C buttons as toggles and they work great. But you have discovered there is no method to know their state, and then take the user to the correct home screen. While I am not seeing the button that triggers that action in your image, I assume there is something that allows the user navigate after making their choices.
Instead of using a component that toggles from state to state, you are going to need create artboard the reflect the state of the choices. Then since you have unique artboards you can then exit and go to the correct homescreen. Does this make sense?
