How did the Mali empire come to an end?

Options:
Rulers lost control of Gao
They were conquered by Axum
Ghana took over their territory
Sundiata was captured by Mansa Muss

The Mali Empire came to an end primarily due to the rulers losing control of Gao, one of their key cities. The decline of the empire was also influenced by internal conflicts, rivalries among different factions of the ruling elite, and the rise of regional powers. However, it is worth mentioning that the Mali Empire was not conquered by Axum or Ghana. Also, Mansa Musa was not responsible for the downfall of the empire, but rather one of its most famous rulers who significantly expanded its territory and influence.
