Final answer:
The CFR is the publication of general and permanent rules and regulations issued by the executive branch's federal agencies, divided into 50 titles that correspond to areas subject to federal regulation. The FCC's regulations, for instance, are in Title 47 of the CFR. The Federal Register publishes new or amended regulations prior to their codification into the CFR.
Step-by-step explanation:
The Code of Federal Regulations (CFR) is D. the publication of general and permanent rules and regulations issued by federal agencies of the executive branch of the U.S. government. These regulations are developed by various agencies to enforce and provide guidelines for legislation passed by Congress. The CFR is divided into 50 titles that represent broad areas subject to federal regulation. Each title is divided into chapters that usually bear the name of the issuing agency. For example, the rules and regulations from the Federal Communications Commission (FCC) are located in Title 47 of the CFR.
Administrative regulations issued by executive agencies have the authority to enforce statutes and often contain details necessary to apply the law in practical situations. The Federal Register is another key document in which new regulations or changes to existing regulations are published before they are codified in the CFR.
