Answer
Both A and R are true but R is not the correct explanation of A.
Explanation
PANs (Personal Area Networks) are small networks used to establish communication between a computer and other devices in proximity, typically up to 10 meters (20 to 30 sq.ft.). On the other hand, a WAN (Wide Area Network) spans a large geographical area across countries and continents. A WAN can cover an area with a radius spanning hundreds of kilometers.
