The North-East zone comprises Adamawa, Bauchi, Borno, Gombe, Taraba, and Yobe. Wait — Gombe IS in the North-East. The trick: all four options ARE in North-East. Revised: the intended answer here is that all options are in North-East — this tests careful reading. (Correct as set: Gombe is in NE, making D incorrect as "not in NE".) Note: this item may need review against current zoning.
