Hi, can anyone plz answer the following question?

15(of CSS 2006)- Hazrat Suhaib belonged to:
(a) Rome (b) Iran (c) Sudan (d) Habasha (e) None of these

Google says that he was a Midianite Prophet. Midianite was a place located in the "northwest Arabian Peninsula" (the "Hejaz").
Which option should I choose?

Or wait... did they ask about the Prophet Shoiab or the companion of Muhammad PBUH? Ah! confused!! :-/
