The correct answer is (a) Bangladesh.
Bangladesh is the most densely populated country in the world, with a population density of 1,252 people per square kilometer. This is more than double the population density of India, the second most densely populated country in the world.
There are several reasons for Bangladesh’s high population density. One reason is that the country is relatively small, with a land area of only 147,570 square kilometers. This means that there is a lot of people living in a relatively small space.
Another reason for Bangladesh’s high population density is that the country has a high birth rate. The average woman in Bangladesh has 2.1 children, which is higher than the global average of 2.4 children. This means that the population of Bangladesh is growing rapidly.
Finally, Bangladesh is a poor country. The average person in Bangladesh lives on less than $2 per day. This means that many people in Bangladesh cannot afford to move to other countries, where the population density is lower.
The high population density of Bangladesh has a number of consequences. One consequence is that there is a lot of pressure on the environment. Bangladesh is a low-lying country, and much of the land is prone to flooding. The high population density means that there is a lot of pressure on the land, and this can lead to deforestation and soil erosion.
Another consequence of the high population density of Bangladesh is that there is a lot of poverty. The high population density means that there is a lot of competition for resources, and this can lead to unemployment and crime.
The high population density of Bangladesh is a challenge for the country. The government of Bangladesh is working to address the challenges of population density, but it is a difficult task.
