The correct answer is (c) 432.
The population density of India is the number of people per square kilometer. It is calculated by dividing the total population of India by the total area of India. The population density of India is 432 people per square kilometer. This means that there are 432 people living in every square kilometer of India.
The population density of India is high because India has a large population and a small land area. India has a population of over 1.3 billion people, which is the second largest population in the world. India also has a land area of only 3.287 million square kilometers, which is the 7th largest land area in the world. This means that India has a population density of over 400 people per square kilometer, which is much higher than the population density of most other countries.
The high population density of India has a number of consequences. One consequence is that India has a high demand for resources, such as food, water, and energy. Another consequence is that India has a high level of pollution. The high population density of India also makes it difficult to provide basic services, such as education and healthcare, to all of the people in India.
The high population density of India is a challenge, but it is also an opportunity. The high population of India means that there is a large workforce available to work in the economy. The high population of India also means that there is a large market for goods and services. The government of India is working to address the challenges of the high population density of India, and it is also working to harness the opportunities that the high population of India presents.
