## **Core Concept**
The National Family Health Survey (NFHS) is a series of surveys conducted in India to gather data on health and family welfare. NFHS-3, like its predecessors, aimed to provide reliable estimates of health and family welfare indicators at the national and state levels.

## **Why the Correct Answer is Right**
NFHS-3 was conducted during 2005-06. This survey provided crucial data on various health indicators, including fertility rates, infant mortality, maternal health, and utilization of health services. The survey was implemented by the Ministry of Health and Family Welfare, Government of India, with technical assistance from IIPS (International Institute of Population Sciences) and funding from the World Bank and other international agencies.

- **Option B:** 1998-99 - This is incorrect because NFHS-2 was conducted in 1998-99.
- **Option D:** 2015-16 - This is incorrect because NFHS-4 was conducted in 2015-16.
