Concept:The Aare-ona kankanfo was the head of the army in the Yoruba system, so the correct equivalent is the military commander in the Hausa/Fulani system.
Explanation:In the Yoruba pre-colonial system, the Aare-ona kankanfo led the army.
In the Hausa/Fulani pre-colonial system, the Madawaki held the position of army commander.
The Waziri acted as the prime minister, while the Galadima oversaw the capital.
The Dogari was responsible for the police.
Since the question asks for the military equivalent, the Madawaki is the correct match.
Answer:B. Madawaki
