Correct answer: A. Yuan Dynasty
Explanation: The direct answer is option A, Yuan Dynasty. Kublai Khan was a Mongol ruler and the grandson of Genghis Khan. After conquering China, he established the Yuan Dynasty in 1271 and ruled as its first emperor, known in Chinese history as Shizu. The reasoning is: Kublai Khan was Mongol, he conquered China, and his Chinese imperial house was called Yuan. Option A is correct. Option B, Ming Dynasty, came after the Yuan and was founded by Zhu Yuanzhang, not Kublai Khan. Option C, Tudor Dynasty, belonged to England and is unrelated to Mongol China. Option D, Bourbon Dynasty, belonged mainly to European monarchies such as France and Spain, not Kublai Khan’s China. Memory cue: Mongol ruler in China equals Kublai and Yuan.
