In A (→FE→GE1→GE2→GE3→GE4) there is no 
raising c
1 to c1 in the chord at the beginning of the bar, which must be an error. Chopin added the necessary sign in FED (as well as the second one "on the run", unnecessary before c in the 2nd half of the bar). The correct text is included also in EE and GE5.
