Human development index include all EXCEPT
**Core Concept**
The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which is used to rank countries into four tiers of human development. HDI is a widely used metric to evaluate a country's overall development and progress.
**Why the Correct Answer is Right**
The HDI takes into account three key dimensions:
* Life expectancy at birth, which reflects the health and well-being of a population.
* Expected years of schooling and mean years of schooling, which measure the education level of a population.
* Gross National Income (GNI) per capita, which reflects the standard of living and economic well-being of a population.
**Why Each Wrong Option is Incorrect**
**Option A:** Not applicable as there is no option A provided.
**Option B:** This option does not exist as there are only four options.
**Option C:** This is incorrect as the HDI actually includes a fourth dimension - income inequality, but it is not a primary component like life expectancy, education, and GNI per capita.
**Option D:** This option is not applicable as there is no option D provided.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that the HDI is a composite index, and a country's ranking can change significantly if any of the three primary dimensions are altered.
**Correct Answer:** C.
