Where does the FCC control government radios?

The Federal Communications Commission (FCC) is responsible for regulating communications by radio, television, wire, satellite, and cable across the United States. This authority extends beyond the continental U.S. to include territories such as Guam, Puerto Rico, and the Virgin Islands. Therefore, the correct answer encompasses all these regions, highlighting the FCC's jurisdiction over government radios in both the United States and its territories.

This regulatory oversight includes managing frequencies, licensing, and ensuring compliance with federal policies related to radio communications, which is essential for effective communication, especially for government operations. The other options are too limited in scope, omitting significant territories under FCC control, which is why they would not be the correct answers.
