Which of the following explains why a country with a high physiological density (e.g., Japan, Egypt, or the Netherlands) risks exceeding its carrying capacity?

А) The population is clustered in key areas, so rural populations will not have easy access to public services such as schools and hospitals
B) The population places a large amount of pressure on the arable land to produce enough food without risking severe environmental degradation
C) The population is evenly dispersed throughout the country, so it is difficult to maintain infrastructure such as roads and telecommunication networks for the entire country
D) There is a large number of people per unit of total land area, so there is no available land for farmers to raise crops and other food products
E) The amount of farmers per unit of land area in these countries is too low to be able to support their populations.​
