Concept:The Kanuri people are historically linked with the ancient Kanem-Borno Empire around Lake Chad, and tradition identifies a specific ruler as their founding father.
Explanation:Ali Ghaji, also known as Ali Gaji, is regarded as the founding father of the Kanuri.
He was a prominent ruler of Bornu in the 15th century.
He moved the capital to Gazargamu, which became the centre of a strong Kanuri state.
This move helped unify the Kanuri-speaking people and laid the foundation for the Borno Empire.
Idris Alooma was a later and very powerful ruler of Borno, but he was not the founder.
Mohammed Yusuf was a modern religious leader, not a historical founder.
Sheik Musa is not recognised as the founding father of the Kanuri.
Therefore, the correct option is Ali Ghaji.
Answer:C. Ali Ghaji
