(D) Geography
(E) Ethnology

Answer 1

The case in which the population of a country grows due to decrease in mortality that is death rate and increase in fertility, also called as natality it is said that the demographic dividend of the country is increasing. The growth increases when resources become unlimited and there is no competition between organisms.

Complete answer:
Human population is the top research study and it is a fascinating field of study. You must be thinking what truly is studied in the human population? So the answer is the human population of a region or a country shows the socio-economic aspect. It tell with which speed and how fast the population is growing, it gives information about the factors that are responsible for growth, it shows that some countries have a high rate of population growth as compared to others, what is the ratio of females to males in a particular region, etc. are some of the aspects of human population study.
Now let us see the details of this option :-
Anthropology :- it is defined as the study of human behaviour . It also includes the societies of humans in the past but not the present . Thus this option is not correct.
Sociology :- it is defined as the study of human behaviour and not human population growth. It includes society , social behaviour , social interactions and culture that interact the people together with each other
Demography :- while studying human population growth some sociological aspects are also taken into account like employment rate . Demography includes mortality , natality , fertility rate . So it includes the study of human population growth.
Geography :- As the name suggests it is the study of relationships of humans with the surrounding environment . It also includes study of places where humans live . Thus this option is not correct.
Ethnology :- it is defined as the study of the characteristics of different organisms and it also involves the study of relationship that is evolutionary relationship between different organisms .Thus this option is not correct.

Our correct option is C) demography.

Note: There is a branch of science that deals with the studying of the human population and this branch is called demography. When there is an increase in population occurs , as for instance there is a large number of individuals in working age groups (in the case of India, it is 15-64 years), or large number of people in reproductive age , it is said that the country is rich in demographic dividend.
