i-485 cross chargeability question

[orgchem]

I am applying i-485 under cross-chargeability. Just wondering how to answer this  question in the i-485.

 

Below is one of the question in I-485

I am applying for an adjustment to permanent resident status because:

Option 1: An immigrant petition giving me an immediate available immigrant visa number that has been approved ( Attach a copy of the approval notice with this application that will give you an immediately available vis anumber, if approved)

Option 2: other basis of eligibility. Explain (for example, I was admitted as a refugee, my status has not been terminated ...so on)

Should I choose the option 1 or 2?

 

can anyone please let me know.

I would answer 1. Explain why you get immediately available number in a letter.
