Final answer:
The correct answer is Askia Muhammad / Mansa Musa.
Step-by-step explanation:
The correct answer is D) Askia Muhammad / Mansa Musa.
Askia Muhammad, also known as Askia the Great, seized power in 1493 and was a ruler of the Songhai Empire. Under his leadership, the Songhai Empire reached its height by adding tributary lands to the east and west, stretching from present-day Nigeria to Senegal.
On the other hand, Mansa Musa was a ruler of the Mali Empire from 1312 to 1337. While he expanded the empire and made it twice the size of Ghana, his reign predates the height of the Songhai Empire.
