Which of the following states was NOT created in 1991?

Analyze the question: We need the state that was NOT created in 1991.

Recall the facts: Nigeria's state creation exercises:

• 1967: 12 states (Gowon)
• 1976: 19 states (Murtala/Obasanjo)
• 1987: 21 states (Babangida), adding Akwa Ibom and Katsina
• 1991: 30 states (Babangida), adding 9 states
• 1996: 36 states (Abacha)

States created in 1991 (9): Abia, Delta, Enugu, Jigawa, Kebbi, Kogi, Osun, Taraba, Yobe.

Check each option:

• A. Abia: created 1991
• B. Akwa Ibom: created in 1987, together with Katsina, so it was NOT created in 1991
• C. Enugu: created 1991
• D. Kogi: created 1991
• E. Osun: created 1991

Answer: Akwa Ibom was carved out of Cross River State in September 1987, so option B is correct.

Tip: Remember 1987 as "AK" for Akwa Ibom and Katsina, the only two states created that year. The 1991 states are Abia, Delta, Enugu, Jigawa, Kebbi, Kogi, Osun, Taraba and Yobe. Also, 1996 gave us Bayelsa, Ebonyi, Ekiti, Gombe, Nasarawa and Zamfara.
