Identify the correct arrangement of the following different types of computer networks in the descending order of their geographic area coverage.

[1] MAN

[2] WAN

[3] LAN

Choose the correct answer from the options given below:

The correct answer is (B), (A), (C) (which corresponds to WAN, MAN, LAN).

To understand why this is the correct arrangement, let us analyze the geographic area coverage of each type of computer network in descending order (from largest to smallest):

1. WAN (Wide Area Network): represented by [2] / (B)
A Wide Area Network covers the largest geographic area, which can span across cities, states, countries, or even the entire globe (for example, the Internet). Therefore, WAN has the largest coverage area.

2. MAN (Metropolitan Area Network): represented by [1] / (A)
A Metropolitan Area Network covers a geographic area larger than a LAN but smaller than a WAN, typically spanning an entire city or a large campus. It serves as a connection network for multiple local networks within a metropolitan region.

3. LAN (Local Area Network): represented by [3] / (C)
A Local Area Network covers the smallest geographic area among the three. It is confined to a localized space such as a single room, home, office building, or school.

Comparing their geographic spans: WAN > MAN > LAN.
Arranging them in descending order (largest to smallest) gives: WAN, MAN, LAN, which corresponds to the sequence (B), (A), (C).
