The Human Development Index (HDI), published annually by UNDP, is a composite of three dimensions measured by four indicators. Which set correctly lists the dimensions?

• A Life expectancy at birth, school enrolment ratio, per capita income
• B Mortality, morbidity, disability
• C Longevity, knowledge, decent standard of living ✓
• D Health, education, gender equity

Explanation

HDI combines longevity (life expectancy at birth), knowledge (mean years and expected years of schooling) and a decent standard of living (Gross National Income per capita in PPP US dollars), combined using a geometric mean. Option A names raw indicators rather than the three dimensions, and option D substitutes gender equity, which belongs to related indices such as GDI and GII, not HDI itself.
