C. Elton's theory
D. None of the above

Answer 1

Sociologists have long looked at the population, issued as central to understanding human interactions, where they have proposed the four demographic theories, to explain the population, and they inform regarding the social thoughts.

Complete answer: Among all demographic theories, a theory which was given by Thomas Mathus has proposed a theory that was based on predictions regarding health and it’s the ability to sustain the growing population, and this theory is called Mathus theory.
According to this Mathus theory, three factors can control the overgrowing or exceeding population, and it’s capacity of the earth, where they are War, Famine, and diseases, and these factors are the positive checks because these factors can increase the death of the population so that the death rate is increased, and they keep the population in check, and at the same time, they have some preventive check which also controls the population by reducing the fertility rates that is birth control.
And this theory also states that people can able to produce so much food every year, but if the population increased to exponential rates, so they thought that people would run out of food and begins to starve, so they would go to war over increasingly scarce resources, and reduce the population to a manageable level.
In the twentieth century, there is another scientist supported the Mathus theory and he states that increasing population on earth may pollute so many natural resources such as water and can damage nature, and the way to reduce that kind of things is by Zero population, which means that the number of population that is dying should be equal to several populations that born on the earth.
So the correct option is B.

Note: On the earth, there is increasing population exponentially and the food that is producing every year may not be sufficient, so they may be a chance to run out of food, and there some checkpoints, which can prevent the exceeding populations, such as diseases, wars, etc.
