Question

what was wang kons greatest achievement?
conquering korea for china
unifying korea under the koryu dynasty
creating a system of moveable type
promoting the ideals of shintoism

Explanation:

Wang Kon (also known as Taejo) founded the Koryu (Goryeo) dynasty and unified Korea. "Conquering Korea for China" is incorrect as he established a Korean dynasty. Moveable type was developed by Bi Sheng in China, not Wang Kon. Shintoism is a Japanese religion, and Wang Kon was involved with Korean Buddhism and Confucianism, not promoting Shintoism.

Answer:

B. unifying Korea under the Koryu dynasty
