What was one factor that eventually led to the demise of the Tang Dynasty? A. The rise to power of a female emperor B. The loss of political control of central Asia C. The expansion into northern and western Asia D. The revival of the civil service examination system

B. The loss of political control of central Asia

Explanation:

The main reason that led to the downfall of the Tang dynasty was the loss of political power fueled by the political tensions that settled within China that led to the weakening of other regions dominated by Chinese power. In addition, the loss of political power led to the creation of an intense crisis, which provoked several rebellions, such as the rebellion of An, the Battle of Talas, among others that brought about the end of the dynasty. With the end of the Tang dynasty, China went through a process of political disintegration.
