Answer: A

The key difference between a microwave radio system and
satellite radiolink system is that microwave transmits along
the line-of-sight, while a satellite radiolink system
operates through transponders placed on the earth's orbit
and a microwave radio system operates on land along the line
of sight. Both microwave and satellite use electromagnetic
radiation and not fiber optic cables for their communication.
