A Local Area Network is designed to cover a limited geographical area such as a room, building or small campus. It provides high-speed connectivity among computers and devices within that confined space. LANs are common in schools, colleges, offices and laboratories for resource sharing. Therefore, this option accurately identifies the network type with a small physical scope.
Option A:
A Metropolitan Area Network covers a city or a large campus spread over tens of kilometres. It is much larger in scope than a single building. Because of this wider coverage, MAN does not best represent the small-area network described in the question.
Option B:
A Wide Area Network spans very large geographical areas, sometimes across countries or continents. The Internet itself is an example of a WAN. Since the question emphasises a single building or small campus, WAN is far beyond the required scope.
Option C:
A Virtual Private Network is a secure tunnel created over existing networks such as the Internet. It describes a method of secure communication rather than the physical size of the network. Hence, it does not directly answer the question about geographical coverage.
Option D:
