D. No. of persons in a village

Answer 1

Hint: Population density refers to a measurement of the number of people living in an area. Population density is calculated by dividing the people according to the area and this represents the number of people living per square kilometer.

Complete step by step answer:
Population distribution is a term used to describe how humans are spread across the earth. The population of people is spread unevenly across the world in a way that some areas are highly populated while other areas are less populated which has an impact on the population density.
Some of the factors that affect the population density are given as follows:
Physical Factors: Areas with extreme climatic conditions, poor natural vegetation, and frequent natural disaster discourage people to reside in those areas leading to low population density and those areas with high land fertility and water supply naturally attracts a higher population.
Economic Factors: Regions with no economic opportunities and poor infrastructure leads to a sparse population and the availability of jobs and better living standard in a given area will ultimately lead to higher population density.
Social Factors: Social problems such as crime or war may discourage people from not settling in an area. Similarly, an area of low crime rates can encourage people to an area leading to high population density.
Political Factors: Poor public services and governmental corruption can lead to low population density and effective public service and a reliable government lead to high population density.
So, the correct answer is Option A.

Note: In the 2011 Census of India, the population density had been 382 persons per square kilometer. The national capital, Delhi recorded a population density of 11,297 thus becoming the most thickly populated union territory and Bihar recorded the highest around 1, 102 population density among the states.
