Why did the first Chinese cities develop on the North China Plain?

C. Freshwater rivers supplied wide-open and fertile farmlands.

Explanation:

In the plains and deltas all across the world the formation of the first cities of the region usually follows a single trait that is present in all of them: it is the existence of freshwater rivers that supply water and have fertile lands drained by them.
