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.

Token-Ring, because it uses a MAU
Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies
