The appropriate answer is B. DIVERGENT. Divergent margins occur where two oceanic plates are pulling apart or it can occur where a Continental landmass is pulling apart.
As oceanic plates pull apart magma up wells from the mantle and new crust is formed along what is called a spreading ridge. The Mid Alantic ridge is an example of a spreading ridge where new oceanic crust is being formed.
China’s geographic location is inherently land bound, as in not near the coast or ocean which hindered sea trading in the past. This hindered their development through trading via sea ports.
