Explanation:

- Option 1: National Bank for Artificial and Rural Development

- Artificial isn't relevant here. NABARD focuses on agriculture and rural development.

- Option 2: National Blog for Agricultural and Real Development

- NABARD isn't a blog. It is a statutory body focused on agriculture and rural development.

- Option 3: National Bank for Agricultural and Rural Development

- This is correct. NABARD was established to provide and regulate credit for the promotion of agriculture and rural development in India.

- Option 4: Nearest bank for Agricultural and Rural Development

- “Nearest bank” isn't appropriate. NABARD operates at a national level with a broad focus on policy and planning for rural development.
