Ania, Do not panic. There is an option for every eligible person. The I-485 is worded obliviously.
You should check the first option IF you married to US citizen and if you file your marriage based I-485 concurrently with I-130, OR your I-130 is already approved.
If you married to GC holder, then you might need to wait for a visa number first.
