I am on F-1 visa since 2006. My wife joined me (with F-2 visa) in 2010. I am filing 1040EZ for 2010. Since my wife doesn't have SSN, I am filing W-7 form to get ITIN for her. Of the options listed below, what description would describe my situation the best?

a. Nonresident alien required to obtain ITIN to claim tax treaty benefit
b. Nonresident alien filing a U.S. tax return
c. U.S. resident alien (based on days present in the United States) filing a U.S. tax return
d. Dependent of U.S. citizen/resident alien
e. Spouse of U.S. citizen/resident alien
f. Nonresident alien student, professor,
g. Dependent/spouse of a nonresident alien holding a U.S. visa
