The correct answer is: C. 10
The population density of Kargil is 10 people per square kilometer. This means that there are 10 people living in every square kilometer of Kargil.
The population density of Kargil is relatively low compared to other parts of India. This is because Kargil is a mountainous region with a lot of uninhabited land.
The population density of Kargil is important because it can affect the development of the region. A low population density can make it difficult to provide basic services such as education, healthcare, and transportation. It can also make it difficult to attract businesses and investment.
The government of India is working to improve the infrastructure in Kargil and to attract more people to the region. This will help to increase the population density and to develop the region.
