The Physical Quality of Life Index (PQLI) developed by Morris is constructed by averaging three indicators. These are:

• A Maternal mortality ratio, under-five mortality rate, and adult literacy rate
• B Infant mortality rate, per capita income, and literacy rate
• C Life expectancy at birth, gross enrolment ratio, and per capita income
• D Infant mortality rate, life expectancy at age one, and basic literacy rate ✓

Explanation

Morris David Morris designed the PQLI using three indicators: infant mortality rate, life expectancy at age one, and basic literacy rate, each scaled from 1 to 100 and averaged. Per capita income appears in HDI and PQLI, not in PQLI, which deliberately excludes economic measures. Option C lists the components of the Human Development Index, making it the strongest distractor for students who confuse the two composite indices.
