The version of FE with d is a result of Chopin's proofreading – there are visible traces of correction in print. It cannot be excluded that the version with c was originally present also in bars 3 and 11, where Chopin corrected it in [A]. It would be then a case of overlooking one place while proofreading a few analogous bars (quite a frequent phenomenon in Chopin's pieces). Both changes in later GE are revisions – in GE2 this figure was assimilated to analogous bars 3 and 11; GE3 returns to the version of the base text, i.e. GC.
