The North China plain is a flatness which has been formed by the time with the sediments of the Yellow river.
As it was not uploaded an image to indicate where this plain is, a picture from google was chosen for this purpose giving some directions on a map of China.
The answer is D) Presence of limited resources in the organization.
The reason being that when there are limited resources in the organization this causes every employee or individual in said organization to desire the posession of optimum resources. This logically increases the level of political engagement in order to get the maximum advantage of the resources and their distribution.
Hope this helps :)
