Concept:Indirect rule is the British colonial system of governing through local traditional rulers instead of direct British officials, rather than imposing a completely new administration.
Explanation:Lord Lugard first implemented the policy of indirect rule in the Northern region of Nigeria.
He chose the North mainly because the area already possessed a well-established Hausa-Fulani emirate system with strong traditional institutions.
The emirs had functioning courts, organised tax collection, and firm authority over their people.
Lugard therefore placed British Resident officers as supervisors, while allowing the emirs to continue exercising day-to-day control.
Kano, one of the most powerful emirates in the North, became a key centre where this policy was first tested and applied under Lugard's administration.
This method proved inexpensive and effective for the British, and it was later extended to other parts of Nigeria.
Answer:Option D: Kano is the correct answer.
