The version featuring c2 introduced by GE (→FE,EE,IE) must be erroneous. Bars 151-153 are filled with a dialogue between diatonic motifs in the keys of E
minor/G major, setting the stage for the transition towards the key of D major abounding in altered leading tones (bars 154-155). Nothing suggests that Chopin would have wanted to disrupt the tonal stability with a temporary allusion to the key of B minor already in the discussed bar.
