Answer:
The correct answer is A. This map depicts the greatest extent of the Mongol Empire.
Step-by-step explanation:
The Mongol empire was established by Kublai Khan and Genghis Khan in the early 13th century. After extensive conquests, in the 13th and 14th centuries, the kingdom comprised most of the Eurasian steppe areas, including China, Russia, Persia, and much of the Middle East and Eastern Europe.
The empire originated from the association of several Mongolian and Turkish tribes in modern Mongolia and grew steadily after Genghis Khan was appointed Mongolian leader in 1206. To its greatest extent, the empire extended from the Danube to the Japanese Sea and from northern Siberia to Cambodia. It covered 24,000,000 square kilometers and ruled over 100 million people.
The empire already began to disintegrate after a succession war between 1260 and 1264. After that, the Golden Horde and several other khans were de facto independent and refused to accept Kublai Khan as their leader. It was not until 1304 that the Mongol khans were reunited, but with the collapse of the Yuan dynasty in 1368, the Mongol empire was finally dissolved.
