Quizplus · Accepted Answer

A multiplexer divides a communications medium into multiple channels so that several nodes can communicate at the same time. A repeater amplifies and regenerates signal while a switch connects multiple devices within a network and facilitates data transfer. A demultiplexer performs the reverse function of a multiplexer i.e. it takes a single input signal and directs it to multiple output channels. Therefore, the best choice for this question is B, which is multiplexer.
