Concept:This question tests your knowledge of current debates on Nigeria's federal system and the popular remedy suggested in recent times.
Explanation:Nigeria operates a federal system of government.
Over time, several issues have challenged this system, such as revenue sharing and state policing.
However, the most widely discussed and seemingly workable solution recently is restructuring.
Restructuring refers to the plan to reorganise Nigeria's political and administrative structures.
It aims to grant more autonomy to states and ensure fairer power distribution.
Terrorism is not a solution; it is a security challenge.
Revenue allocation is an issue, not a wide-ranging structural solution.
State police is often proposed but not as broad as restructuring.
Hence, restructuring is the most acceptable answer.
Answer:B. restructuring
