To provide an accurate answer, I would need to know the specific factors you are referring to (A, B, C, and D). However, generally speaking, several key factors contributed to the downfall of the Songhai Empire, including:
- Internal Conflict: Political instability and succession disputes weakened the central authority.
- Economic Decline: The empire faced economic challenges due to shifting trade routes and competition.
- Military Defeats: The defeat by Moroccan forces in 1591 using gunpowder technology marked a significant blow.
- Cultural and Religious Divisions: Tensions between different groups within the empire could have contributed to its fragmentation.
If you provide the specific options (A, B, C, D), I can help identify the correct one.
