Which entities are primarily governed by the FAR?

The Federal Acquisition Regulation (FAR) primarily governs federal executive agencies and certain government contractors involved in acquiring goods and services for the federal government. The FAR establishes the rules and procedures that these agencies must follow when soliciting and awarding contracts, ensuring that procurement processes are consistent, transparent, and competitive.

Federal executive agencies, which include departments like Defense, NASA, and Homeland Security, are explicitly required to adhere to FAR guidelines during their procurement activities. Additionally, contractors that do business with the federal government are also subject to the FAR when their contracts involve procurement actions that meet the defined thresholds and activities outlined in the regulation.

State and local government agencies are not governed by the FAR; they have their own procurement regulations and practices. Similarly, while private sector corporations engage with the federal government, the FAR does not govern them as standalone entities unless they are acting as contractors under government contracts. International organizations are generally not subject to FAR regulations as they operate under different frameworks established by international agreements and treaties.

Thus, the focus of the FAR on federal executive agencies and their contractors makes C the correct answer to the question.
