I've been player A. Several people i refuse to play with because of previous experiences with them in a game. It actually caused me to leave an online group where I really liked ~8 of the people because 2 made my time there miserable.
Earlier than that, I had an experience at an in-person game that lead the DM's boyfriend to tell me later on that he would have punched the "player B" if he were in my shoes. In that case, all the others understood I would never play with her again, and were more than willing to choose me over her for future games.
So, I'd say if Player's A's concerns are legitimate...you should take player A and probably wouldn't want player B in your game anyway. If Player A's concenrs don't seem justified, invite both and don't let A stop B from playing.
