Concept:The Hausa/Fulani Empire managed its diverse population through a decentralised but unified administrative system.
Explanation:The empire contained many ethnic groups, so it could not concentrate all power in one place.
To rule effectively, it shared authority among different offices and local rulers.
For example, the Sarkin Fada headed palace workers, while the Waziri served as prime minister.
These officials exercised delegated powers under the overall central authority of the empire.
This system combined central leadership with devolved responsibilities.
Therefore, it is best described as a quasi-federal structure with devolution.
Answer:C. A quasi federal structure with devolution.
