AP form

my case is 485 pending, now I am filing I-131, which box I should check in part 2?

a.I am a permanent resident or conditional resident of the United States and I am applying for a reentry permit.

b.I now hold U.S. refugee or asylee status and I am applying for a refugee travel document.

c.I am a permanent resident as a direct result of refugee or asylee status and I am applying for a refugee travel document.

d.I am applying for an advance parole document to allow me to return to the United States after temporary foreign travel.

Thanks.
