Concept:The question tests knowledge of the Nigerian states created by General Sani Abacha.
Explanation:General Sani Abacha created six new states in
1996.
They were Bayelsa, Ebonyi, Ekiti, Gombe, Nasarawa, and Zamfara.
This increased the total number of states in Nigeria to
36.
Among the options, Ebonyi, Gombe, and Ekiti were created by Abacha.
Katsina was not among them because it had already been created in
1987 by Ibrahim Babangida.
Hence, the state that was not created in Abacha's regime is Katsina.
Answer:D. Katsina
