Which option to chose

[pstnofpwr]

I'm will be filing for my citizenship and need to know which option to choose so that I can proceed. Both apply to me hence the confusion:
A. Have been a lawful permanent resident of the U.S. for at least 5yrs
B. Have been a lawful permanent resident of the U.S. for the last 3yrs. In addition, you have been married...

Thanks in advance
