The Form I-485 Supplement A (Rev.01/18/2011) indicates "I am filing Supplement A to Form I-485 because (a).....(b) I am the beneficiary of a visa petition filed on or after January 15, 1998 and on or before April 30, 2001" Please make sure you are using the right version of the Form. If the petition on her behalf was filed before April 30, 2001, then selecting [b] is the correct response. Please hire an immigration lawyer to help you.

You should always consult with an experienced immigration attorney to make certain that the advice you received is appropriate for your particular immigration case.
There is much more to a successful immigration case then just completing forms. Additionally, not only can incorrectly completing the forms lead to disastrous results, USCIS does not refund money when it denies applications or for applications that are filed which are ultimately not needed. I suggest you consult with an experienced immigration attorney who can review your case and advise you the best way to proceed.
