Which organization is responsible for overseeing regulations related to agricultural inspections?

The correct response highlights the role of the United States Department of Agriculture (USDA) in overseeing regulations related to agricultural inspections. The USDA is responsible for ensuring that agricultural products meet safety standards and regulations, which includes the inspection of imports and exports to prevent the introduction of pests and diseases that could harm American agriculture or the environment. This agency plays a crucial part in monitoring food safety, inspecting meat, poultry, and egg products, and regulating plant and animal health.

The other organizations listed have specific duties that do not encompass agricultural inspections. Customs focuses on border security, trade compliance, and enforcing customs laws, but it is not primarily responsible for agricultural regulations. The Federal Aviation Administration is charged with regulating civil aviation and airspace, which does not include agricultural inspections. The National Transportation Safety Board investigates transportation accidents across various modes but does not oversee agricultural regulations. Thus, the USDA's specific mandate and expertise make it the authoritative body for agricultural inspections.
