C. the Qin dynasty

Explanation:

The Qin dynasty is considered to be the first dynasty of Imperial China. This dynasty emerged on the scene and managed to create a real dynasty after several conquests. The conquests were of the seven warring states, which were small states in ancient China that were constantly in war with each other. The Qin were more powerful than each of these small states at the time being, so one by one they managed to take over their territories, putting end to the period of wars and instability. Once all these territories were conquered, the Qin created one unified territory, and to avoid problems with local powerful leaders, this dynasty centralized the power in the capital. The territory that the Qin controlled were the valleys of Yangtze and Huang-he, Taiwan, part of southern China, part of Inner Mongolia and big portion of the eastern coastline.
