B. Central Leather Research Institute | 2. Chennai
C. National Institute for the Mentally Handicapped | 3. Bangalore
D. National Institute of Immunology | 4. Secundrabad
| 5. New Delhi

The correct answer is Option 3 (A-3, B-2, C-4, D-5) based on the following institutional locations:

• A. Indian Institute of Astrophysics (3): Headquartered in Bangalore, it is a premier autonomous research institute under the Department of Science and Technology.
• B. Central Leather Research Institute (2): Located in Chennai, it is the world's largest constituent laboratory of the CSIR dedicated to leather research.
• C. National Institute for the Mentally Handicapped (4): Now known as NIEPID, it is situated in Secunderabad and functions under the Ministry of Social Justice and Empowerment.
• D. National Institute of Immunology (5): This elite research body is located in New Delhi.

Options 1, 2, and 4 are incorrect because they mismatch these established geographic locations, such as incorrectly placing the IIA in Secunderabad or the CLRI in Agra.
