Another officer told my wife the consular officer is suspicious about my marriage and cannot give a visa, I don't know why because she answered all questions asked. What way forward should I take. Any advice will be appreciated. Thanks

We got married in 2018 after I got my DV1 visa, I'm still a green card holder. I filed as single on my tax returns because my wife is not in the US yet and hasn't got a social security number and did not see that as mandatory but noted

Thanks Kor2USA. 
Her answers were not inconsistent she told me
For cohabitation I didn't think proof was necessary but thanks noted
My parents lived in the village at the time me and my wife were living together in the city
I have lived with my Aunt and Uncle since age 6 and they educated me through my secondary and highschool education. I began doing business after highschool
we got married in our hometown not elsewhere
Yes my wife met my Aunt and Uncle a couple of times but we didn't really think of pictures
I proposed to my wife on her birth day before we started living together but there was no engagement party.
