Answer: A

A ring or loop topology would enable messages to be rerouted
should the network cabling be severed at any point or a
hardware element fail. With the correct settings in network
hardware, the loss of any link would be invisible to the
users. In line and bus networks, which are essentially the
same thing, terminals are connected to a single cable. If
this cable is severed, all terminals beyond the point of
severance will be unavailable. A star network clusters
terminals around hubs, connected to the server by separate
lines in the form of a star. If any line is severed, all
terminals in the cluster at the end of that line would be
disconnected.
