The frequency range for the broadcast satellite service is  

• The ku-band typically covers the frequency range of approximately 12 GHz to 18 GHz. It is commonly used for satellite communication, including broadcast services and VSAT (very small aperture terminal) systems.
• This frequency range allows for efficient data transmission for applications such as broadcasting, broadband internet, and satellite television.
• ku-band also allow for the use of smaller antennas, contributing to more compact and cost-effective satellite communication systems.

Here, option 4 is correct.
