The authenticity of the version with d
is practically excluded. GE2 was released after Chopin's death and it cannot include any authentic versions, which would not be present in the previous sources. The only possibility, actually theoretic, would have been the following scenario concerning EE2 – the sharp before the bottom note of this chord, perhaps present in the manuscript base text to EE1, could have been overlooked in this edition, which was corrected in EE2 (→EE3). However, an arbitrary addition performed by the reviser of EE2 is much more likely:

The only possibility, actually theoretic, would have been the following scenario concerning EE2 – the sharp before the bottom note of this chord, perhaps present in the manuscript base text to EE1, could have been overlooked in this edition, which was corrected in EE2 (→EE3). However, an arbitrary addition performed by the reviser of EE2 is much more likely: - numerous additions of accidentals – mostly justified – constituted one of the main topics of revision of EE2 in the entire Op. 25;
- except for the changes ordering the text in EE2, numerous, entirely arbitrary additions were introduced, e.g., fingering, such as in bars 1-2 and 45-48, or performance indications – cf., e.g., the Etude in F minor, No. 2;
-
among the not so obvious additions of accidentals introduced in EE2, the
added in bar 26 of the Etude in G minor, No. 6 appears in a similar melodic context; -
the reviser could have considered the
in the next bar – written probably due to the simultaneously stroke d1 in the R.H. – to be a signal that there should be a 
before the discussed note; -
in the discussed place seemed to be somehow justified also to the independent reviser of GE2;
-
introduction of d in the discussed chord deprives the bass line of the so characteristic for leading voices in this Etude repetition of the sound at the beginning of the next bar.
In the main text, we provide the undoubtedly authentic d with a cautionary natural.
