What are the required elements of a station identification?

The correct choice highlights that a station identification requires the call letters followed by the city of license. This format is essential for ensuring clear communication between the station and its audience, as well as for regulatory compliance.

The call letters serve as the unique identifier of the station, making it easy for listeners to remember and recognize the broadcaster. Following this with the city of license provides a geographical context, which is important for locating the station on the dial and understanding the area's audience. This practice aligns with the regulations set forth by the Federal Communications Commission (FCC), which dictates how broadcasters should identify themselves to ensure listeners are informed about where the programming is originating.

Thus, using this specific order—call letters first and the city of license second—ensures clarity and meets the necessary legal requirements for broadcasting.
