The correct answer is (a) West Bengal.
As per the 2011 Census, the population density of West Bengal was 1028 persons per square kilometer, which is the highest among all the states of India. The population density of Kerala was 858 persons per square kilometer, followed by Uttar Pradesh with 828 persons per square kilometer and Bihar with 1102 persons per square kilometer.
The population density of a state is the number of people living in a square kilometer of that state. It is calculated by dividing the total population of the state by the total area of the state. The population density of a state can be used to measure the level of urbanization in that state. A high population density indicates that the state is highly urbanized, while a low population density indicates that the state is less urbanized.
The population density of West Bengal is high due to a number of factors. One factor is the state’s location in the Ganges Delta. The Ganges Delta is a fertile region that is ideal for agriculture. This has led to a high population of farmers in the state. Another factor is the state’s proximity to Bangladesh. Bangladesh is a densely populated country, and many people from Bangladesh have migrated to West Bengal in search of better opportunities.
The high population density of West Bengal has a number of implications. One implication is that the state faces a shortage of resources, such as water and land. Another implication is that the state faces a problem of pollution. The state’s cities are often congested and polluted.
The government of West Bengal is taking a number of steps to address the problems associated with the state’s high population density. One step is to promote industrialization. Industrialization will create jobs and help to reduce the number of people who are dependent on agriculture. Another step is to improve the infrastructure of the state’s cities. This will help to reduce congestion and pollution.
