Most of the population in East Asia is clustered in central China.

Explanation:

China stands at first place in the world population rankings of countries. The central part of China is densely populated and most of China's population is concentrated in the central part of China itself. Huge rivers like River Han, River Wei, and River Min flowing through central China have brought prosperity to the region. That is majorly why, most of the East Asian population is clustered in central China.

I believe that it is C. In central China because that's also where Japan and North Korea are
