What geographic feature lies at the center of Africa's table land?

The Congo River Basin is a significant geographic feature at the center of Africa's table land. It is a large and intricate network of rivers, encompassing the Congo River and its tributaries, which drains a substantial portion of Central Africa. This basin is characterized by low-lying floodplains, dense rainforests, and unique biodiversity, making it one of the most vital ecological regions on the continent.

The Congo River itself is the second longest river in Africa and plays a crucial role in the hydrology of the region. The basin's significant size and diverse ecosystems contribute to its centrality in Africa's geography, providing a critical source of water, transportation, and livelihoods for millions of people.

In contrast, the other options represent significant geographic features, but they are not positioned at the center of Africa's table land in the same way. The Nile River Delta, located in northeastern Egypt, is far from the central highlands and has distinct geographic and cultural characteristics. The Great Rift Valley, while a significant tectonic feature, stretches primarily through East Africa rather than being a central feature across the continent. Lake Victoria, which is the largest lake in Africa, is also situated in the eastern part of the continent, bordered by Uganda, Kenya, and Tanzania
