• B. NIH
• C. EPA
• D. FDA

Answer: (B)

The main idea here is recognizing which organization is best known for conducting and funding biomedical research. The National Institutes of Health, NIH, is the United States’ principal biomedical research agency. It runs intramural laboratories and funds a vast network of researchers across universities and medical centers, supporting basic science, translational studies, and clinical research. This scale and focus on advancing health science is why it’s considered one of the world’s foremost research centers in health and medicine. While USDA works on agriculture and food systems, EPA focuses on environmental protection and related science, and the FDA oversees safety and regulation of foods and drugs, NIH stands out as the leading biomedical research hub.
