I don't know what to check off for race on college applications

I am from North Africa, specifically Libya, and consider myself Arab, but most college applications do not have an option to check off for North African/Middle Eastern. What should I check off if there is no “other” option? I don’t know if White or African American describe me and I don’t want to check something off incorrectly. Thank you!

For the Common App, you check “white” and for the follow-up question “Which best describes your White background?” you check “Middle East.” Or instead of Middle East, you can check “Other” and write in “North Africa.” The Coalition App is similar.
