The correct answer is: d) All of the above
HDI stands for Human Development Index. It is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A higher HDI indicates a better quality of life.
Districts within Arunachal Pradesh likely show variation in their HDI scores due to a number of factors, including:
- Differences in infrastructure development: Some districts have better access to roads, electricity, and other infrastructure than others. This can make it easier for people to get around, access education and healthcare, and participate in the economy.
- Unequal access to social services: Some districts have better access to education, healthcare, and other social services than others. This can lead to differences in health outcomes, educational attainment, and economic opportunities.
- Cultural and geographic factors: Some districts have different cultures and geographic features than others. This can lead to differences in values, beliefs, and practices, as well as in the availability of natural resources.
All of these factors can contribute to variation in HDI scores between districts within Arunachal Pradesh.
