I 485 RFE for Birth Certificate

Hello Sajhaitis, I received an RFE for Birth Certificate from USCIS. I did include the Birth Certificate prepared by the municipality ( it was prepared recently) with my application package, but now they are asking for RFE. At this point, I have the following documents with me: Relationship verification document from the municipality, Same Birth Certificate that I sent with the application School, High school character certificates (in English) with father's name, DOB (both Nepali and English), and place of residence at the time of certificate issuance. What else would I need to include or prepare in order to get this RFE through? Suggestions are highly appreciated. Best.
