All three indicators (1, 2, and 3) are used by IFPRI (International Food Policy Research Institute) to compute the Global Hunger Index Report.
The Global Hunger Index (GHI) is a tool designed to comprehensively measure and track hunger at global, regional, and national levels. It's a peer-reviewed annual report, now jointly published by Concern Worldwide and Welthungerhilfe.
Purpose: To assess hunger severity and track progress towards ending hunger.
Each country's GHI score is calculated based on a formula that combines four indicators that together capture the multidimensional nature of hunger
- Undernourishment - The share of the population whose caloric intake is insufficient;
- Child Stunting - The share of children under the age of five who have low height for their age, reflecting chronic undernutrition;
- Child Wasting - The share of children under the age of five who have low weight for their height, reflecting acute undernutrition; and
- Child Mortality - The share of children who die before their fifth birthday, reflecting in part the fatal mix of inadequate nutrition and unhealthy environments.
Hence, option C is the correct answer.
