The text of A is generally correct. Lack of the  before the 2nd note is however most probably a result of Chopin's distraction (haste). It is revealed by the place before the note, most probably left for the accidental to be inserted and, above all, by a later proofreading of FE (→GE,EE), in which both the  and the cancelling it  before the 8th semiquaver were added. It is not the only omission of an accidental introducing alteration of this kind in Chopin's works, although it rarely occurs (e.g., in the Etude in F minor, Op. 25 No. 2, bar 56).

b. 80

composition: Op. 10 No 12, Etude in C minor

Plain minim in A (→FE→GE1,EE#)

Dotted minim in GE2 (→GE3→GE4)
..

The missing dot extending the c2 minim is, according to us, the composer's error. Chopin would often extend or separate some of the notes with additional stems or ties without taking care of the rhythmic values of these "voices" to fill the entire bar. However, in this case the rhythmic gap concerns the main melodic line, which was rather not intended, as Chopin embraced it with a slur. The mistake was corrected in GE2 (→GE3→GE4) and EE4.
