The correct answer is:
The Yuan Dynasty.
The Mongol dynasty was called the Yuan Dynasty and had been in place since the 13th century CE. It was overcome in 1368 by the Ming dynasty that ruled China from 1368 to 1644 CE. The Yuan remains left to Mongolia after the fall of Yingchang to the Ming in 1370. There, the name Great Yuan was formally carried on as the Northern Yuan dynasty.
