A higher HDI score generally indicates:

The correct answer is: D) Better quality of life.

The Human Development Index (HDI) 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 score generally indicates a better quality of life for citizens of a country.

Option A is incorrect because a higher HDI score indicates a higher standard of living, not a lower one.

Option B is incorrect because a higher HDI score indicates better access to essential services, not limited access.

Option C is incorrect because a higher HDI score indicates lower inequality, not higher inequality.

I hope this helps!
