A Correct answer
Explanation

Cellular phones get their name from the cellular system architecture where geographic areas are divided into hexagonal 'cells' each served by a base station. As a user moves between cells, the call is handed off to the next cell's base station, enabling continuous communication. This cellular division allows for efficient frequency reuse and expanded network capacity.
