Final answer:
The FCC is responsible for agent licensing and administrative supervision when it comes to radio and television broadcasters, as they handle the licensing and regulations for the airwaves.
Step-by-step explanation:
The entity responsible for agent licensing and administrative supervision varies based on the particular sector of industry or service. For example, the Federal Communications Commission (FCC) is the agency that oversees and regulates the airwaves, including licensing for radio and television broadcasters.
The SEC, or Securities and Exchange Commission, on the other hand, regulates financial markets, including the stock exchanges and securities industry. Meanwhile, the FDA, or Food and Drug Administration, manages regulations related to food and drugs safety, and the FAA, or Federal Aviation Administration, oversees aviation-related activities, including the licensing of pilots.
