Which statement best describes the role of a satellite in communication?

The best description of the role of a satellite in communication is that it functions as an intermediary to amplify and relay signals. This means that satellites are positioned in orbit around the Earth and receive signals from ground stations, which they then amplify and retransmit to other locations on the planet. This capability allows for long-distance communication and broadcasting that would be challenging to achieve directly from ground stations, especially in remote or hard-to-reach areas.

Satellites play a crucial role in providing services such as television broadcasting, internet connectivity, and telephone services, effectively bridging vast distances and facilitating communication across countries and continents. By acting as an intermediary, satellites enable the exchange of information over large geographic areas, making them essential to modern communication networks.

This option highlights the satellite's primary function within communication systems, distinguishing it from other capabilities that do not accurately reflect how satellites operate in this context.
