How Many Years After Marrying A US Citizen One Can Apply For

[GreenCard]

I got my conditional permanent resident card (with 2 years condition) after 9 months of my marriage with a US citizen spouse. My question is that how many years do I have to wait exactly to apply for US citizenship, provided me and my spouse live together all time and our marriage is in good faith?

(A) 3 years since the date of my marriage?

(B) 3 years since the date conditional permanent resident card was issued to me?

(C) 3 years since the date permanent resident card (card with no condition valid for 10 years) will be issued to be?

(D) 5 years since the conditional permanent resident card was issued to me? (2 years of conditional resident card + 3 years of non conditional permanent resident card)

Please do not guess if you are not 100% sure because such an answer will create more confusion instead of help. If you think that none of the given options is a correct answer, please add another option. I will appreciate for your advise!
