Incomplete birth certificate - Parents dates and places of birth missing

[GMP 0]

I am Italian on F1-OPT status and I am going to apply for Adjustment of Status through marriage. My father just obtained a (A) birth certificate for me from the Italian office: besides my full name, date, place of birth, it presents full legal names of my parents, but NOT their dates/places of birth. The Italian office said that this is the format they do and cannot be modified. So, my father further got another certificate (B) "family status" which displays the components of his family, that is him, my mother, me, and my sisters, with full names and dates and places of birth of all of us. Moreover, he also got (C) his "marriage certificate" where dates and places of birth of him and my mother are displayed. 

Would any of (A)+(B), or (A)+(C), or (A)+(B)+(C) be accepted as a replacement of a complete birth certificate (as US format)? 

Thanks!

You don’t need to have places of birth of your parents on your birth certificate. Only their names. Your birth certificate is what it is. Every country is different. There’s no requirement on what a birth certificate has to have in order to be valid.
