Correct Answer : Option (C) - To receive and redirect communication signals

A communications satellite works like a relay station: signals transmitted by the ground stations are picked up by the satellite’s receiver antennas, the signals are filtered, their frequency changed and amplified, and then routed via the transmit antennas back down to Earth. The redirected signals are received by ground stations, also called earth stations and further processed to extract the base band signals.
