The version of the 4th quaver with b2 cannot be authentic, as the 
visible before this note in GC and FE1 (→FE2→EE1) was probably supposed to concern the bottom note of the third, g2 (the revisers of GE and EE2 added another here, considering its absence a common oversight). It is proved by a comparison with analogous bars – in all the remaining places (bars 137, 143, 145 and 147-149) the top voice of the dyads is led diatonically, without raising the note on the 4th quaver in the bar. It is confirmed by the Chopinesque proofreading of FE3 (→FE4), in which the sign was moved before the bottom note, which proves that the composer heard here g2-b
2. On the other hand, if g2-b2 had really been intended by Chopin from the very beginning, the in [A] would have probably been misplaced, since two persons – the copyist and the engraver of FE1 – misinterpreted it.
