The answer is B. Sahara Desert.

To find the major geographical feature that was just to the north of the ancient African empires, we can use historical and geographical knowledge about the region. The options given are the Nile River, Sahara Desert, Andes Mountains, and Mount Kilimanjaro.

A. The Nile River: The Nile River is a significant geographical feature of Africa, but it primarily runs through Egypt, which is located in the northeastern part of Africa. It is not directly north of the ancient African empires.

B. The Sahara Desert: The Sahara Desert is the largest hot desert in the world and stretches across northern Africa. It covers a vast area, including a significant part of North Africa, including the region directly north of the ancient African empires.

C. The Andes Mountains: The Andes Mountains are located in South America, spanning several countries along the western coast of the continent. They are not in Africa, so this option can be excluded.

D. Mount Kilimanjaro: Mount Kilimanjaro is the highest peak in Africa and is situated in Tanzania, which is located in East Africa. It is not directly north of the ancient African empires.

Therefore, the correct answer would be B. Sahara Desert.
