National Dairy Research Institute is established at

The correct answer is A) Karnal. The National Dairy Research Institute (NDRI) is an ICAR institute located at Karnal, Haryana, and it has deemed-university status. It began in 1923 as the Imperial Dairy Institute at Bangalore and was moved to Karnal in 1955, when it took its present name. The core concept is the location of ICAR institutes, which aspirants are often asked to match with their states.

• Hisar (B): Hisar hosts CCS Haryana Agricultural University and LUVAS, the veterinary and animal sciences university. NDRI is not there.
• Anand (C): Anand is the home of the cooperative dairy model. NDDB and AMUL are there, but NDDB is a statutory body under the NDDB Act, 1987, and not the research institute.
• Jaipur (D): Jaipur has no ICAR dairy research institute. Rajasthan's veterinary university is at Bikaner.

For Mains, connect this to the White Revolution, Operation Flood and the cooperative model of Verghese Kurien, along with the role of research in dairy productivity and farmer incomes.

Trap: Aspirants often pick Anand because they associate it with dairy. Keep NDDB and AMUL separate from NDRI, which is a research body at Karnal.
