Which evaluation metric combination would best judge whether a nutrition intervention reduced both immediate undernourishment and longer‑term risk of stunting?

• A. Short‑term: national GDP growth rate; Long‑term: number of hospitals built in the region, since economic growth and infrastructure are assumed to directly reflect nutritional improvements.
• B. Short‑term: number of social media posts about the program; Long‑term: changes in adult height measured in the same year as intervention completion, because immediate adult height changes will show program success.
• C. Short‑term: prevalence of wasting and percentage of households reporting food consumption adequacy; Long‑term: change in stunting prevalence among children under five and school enrollment/cognitive assessment proxies, collected at baseline and follow‑up.
• D. Short‑term: counts of food parcels delivered; Long‑term: number of agricultural research papers published about the region, assuming dissemination equates with impact.

Answer: (C)
