What does USDA stand for?

The correct answer is the full name of the USDA, which is the United States Department of Agriculture. This governmental department plays a critical role in overseeing various aspects of farming, forestry, and food systems. Its responsibilities include supporting agricultural production, ensuring food safety, and managing nutrition programs. The USDA also conducts research and provides economic analyses related to agriculture, all of which are pivotal for policymaking and support for American farmers.

The other options do not accurately represent the complete and official title of the department and thus fall short in capturing the broad scope of the USDA's functions and responsibilities. Understanding this term is important, as it underpins key agricultural policies and programs that impact the economy and food supply in the United States.
