A Wide Area Network is the best for he given scenario. The reason is:
A wide area network (WAN) is a network that exists over a large-scale geographical area. A WAN connects different smaller networks, including local area networks (LANs) and metro area networks (MANs). This ensures that computers and users in one location can communicate with computers and users in other locations. 
WANs are similar to a banking system, where hundreds of branches in different cities are connected with each other in order to share their official data.

Star Topology is laid out physically in this scenario. The reason is:
In this type of topology all the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node.
So here, if one link is broken down, the other will work smoothly because all the connection are independent to the central hub.
