None of those. It'll be either the player is forced to sit out for a period of time (while still being blinded off) or if they keep doing it and the tournament director thinks it's warranted they can be kicked out of the tournament and their chips can be removed from play.
That's got nothing to do with this situation though, because the action was not
out of turn. FWIW it was a bet too, not a raise. But that's just nitpicking. A checked, B checked, then A bet dark for the next street. All the action is in turn.
