Ethernet and Token-Ring are the two most commonly used network architectures in the world. Jim has heard of the different topologies for networks and wants to choose the architecture that will provide him with the most options. Which of the following would that be? Choose the most correct answer.

Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies
Ethernet, because it can be set up with most topologies and can use multiple transfer speeds
Token-Ring, because it uses a MAU
Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology
Ethernet, because it is cabled using fiber-optic cable
