what do you mean by a or b? filing date and final action date?

yes, A final action date, B Filing Date

After the I-360 is approved, those who have not yet filed the I-485 must submit their application according to the applicable filing date. Those who have already filed the I-485, however, follow the Final Action Date for adjudication. This is not about Chart A or Chart B.

thanks, very helpful
