Correct Answer: B
Solution :
It is done with the help of Artificial Satellites. Artificial Satellites are objects launched from earth to orbit earth or other planets. These Satellites are used for communication, remote sensing, weather forecasting, and other purposes. Our daily and live television is beamed to us through satellites. These satellites also help to digitally spread radio waves and wireless internet.
