Answer 1

The correct option is D All of the above

Global Positioning System(GPS) is a global navigation satellite system (GNSS) that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft.

A satellite is an artificial body placed in orbit round the earth or another planet in order to collect information or for communication.

Clearly all of them are examples of communication systems.
