Which of these is the best explanation for the high population density in china's eastern regions?
a) the region is not capable of supporting large scale farming.

c) the region was traditionally home to the emperor and the gods.
d) the region was destroyed by civil war which caused people to leave.

B) The region is close to the ocean and has a favorable climate.

China's eastern regions are close to the ocean and have a favorable climate, which is suitable for agriculture. This has likely led to the high population density of the region. As the population in the area increased, so did infrastructure, with many cities becoming more modern. This, in turn, continues to contribute to the high population density of the region.
