b. rapidly assimilated into Chinese society.
Explanation:
The Yuan dynasty was the dynasty established by Kublai Khan, a Mongolian leader. This was the first time a foreign-born ruler had ruled all of China. Kublai Khan effectively conquered China by 1279, but he claimed his grandfather Genghis Khan was the official founder of the dynasty. One of the ways in which the Mongols were able to exercise control over China was by rapidly assimilating into Chinese society. Kublai Khan set up a civil administration, built a capital within China and supported Chinese religions and cultures.
