The A version must be erroneous – if the penultimate quaver were supposed to be a d2, there would be no reason for writing a  to the next note or anywhere else in this bar. Therefore, this is one of the very rare situations in which Chopin did not overlook an accidental cancelling an alteration, but the one defining it. This is how it was interpreted in GE (→FE,EE,IE), and this is the version we adopt to the main text.

c2 in A (contex­tual interpretationGEFE,EE,IE)

In A the middle note of the 2nd triplet is devoid of an accidental, which gives c2. What is more, the  defining c2 is before the 2nd semiquaver of the nonuplet further on in the bar, which seems to confirm the fact that the discussed note should be a c2. On the other hand, a strong argument for an oversight of the  before this note is provided by the penultimate semiquaver in the bar, b1, and not b1 – the 1st and 2nd beat is a transposition of the 4th and 5th beat by a second up (from F to G), and the counterpart of this b1 in the analysed place is c2, and not c2.

In the main text we add a  restoring b1 on the 4th beat of the bar, overlooked by Chopin. None of the editions noticed this patent mistake.
