Best answer
The correct answer is (d) 36000km

The explanation is: Satellite broadcasting takes place between directional parabolic antennae, where the signal is sent via cable to antennae which beams it to the satellite and then the satellite sends back a signal to another location on Earth. A communication satellite amplifies radio telecommunications signals with the help of a transponder. The distance between it and earth’s surface is approximately 36000km.
