Octaves & c in AI

The bass notes in bars 83, 85 and 87 varied in the earlier version – in bars 83 and 87 C-c octaves, while in bar 85 a single c note. Chopin standardised it in the published version, probably to emphasise the effect of repetition, being the first signal of harmonic stabilisation leading to the ending of the piece.
