B. The region experienced a surplus of food

Explanation:

The Nile River Valley is one of the places where the earliest civilizations developed. The main reason for this was that the region was providing the people living there with a surplus of food, thus they had much more spare time to specialize in other sectors. The surplus of food was due to the Nile River, as the river had annual flooding, and when it was flooding it was delivering new fertile deposits, thus making the soil very good for large scale agriculture, which the people used it in their advantage.
