Performance of components of PQLI is counted between –
**Core Concept**
The Physical Quality of Life Index (PQLI) is a composite index that measures the quality of life in developing countries. It combines three basic indicators: literacy rate, infant mortality rate, and life expectancy at age one. The PQLI aims to provide a comprehensive assessment of a country's well-being beyond its GDP.
**Why the Correct Answer is Right**
The PQLI is a multidimensional index that captures various aspects of a country's development. Literacy rate reflects the level of education and human capital, while infant mortality rate and life expectancy at age one indicate the health status of the population. By combining these indicators, the PQLI provides a more nuanced understanding of a country's quality of life. The index is particularly useful for international development and humanitarian work.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify the correct range or interval for PQLI scores. PQLI scores range from 0 to 100, with higher scores indicating better quality of life.
**Option B:** This option is incorrect because it does not accurately describe the components of PQLI. While GDP per capita is an important economic indicator, it is not one of the components of PQLI.
**Option C:** This option is incorrect because it does not specify the correct range or interval for PQLI scores. PQLI scores range from 0 to 100, with higher scores indicating better quality of life.
**Clinical Pearl / High-Yield Fact**
The PQLI is a useful tool for policymakers and development agencies to assess the impact of their interventions and prioritize resource allocation. It highlights the importance of investing in education, healthcare, and human capital to improve the quality of life in developing countries.
**Correct Answer: D.**
