What is my race? Please help!?

I know that sounds really dumb, but I have to know for a OAT test.(Ohio Achievement Test) I'm part Indian, and we need to put down our race, and Indian is not on there. There is White, Black, Asian, Hispanic, Native American, and Native Alaskan/ Islander. But no indian! So I know I have to put down white for the European part of me, but what would my race be for the Indian part? Asian? Please help!!!
