The correct option is D
The Egyptians called their country Kemet. The European Egyptologists translated it as "the black earth", as opposed to the ocher color of the desert, which corresponded to that area in which the lands were fertile due to the black silts deposited after the annual flooding of the Nile River, a vital artery of the civilization of Ancient Egypt.
The Area of arable land was considerably smaller, but very fruitful. It occupies the space around the entire valley and the West Nile delta.
