Quizplus · Accepted Answer

A multiplexer is an electronic device that selects and switches between multiple input signals and directs the selected output signal to a single line. In car audio systems, a multiplexer is used to switch between different audio sources (e.g. radio, CD player, Bluetooth, etc.). Therefore, option A is the best choice. The hands-free module is used for Bluetooth calling, the radio choke is used to filter out interference in the radio signal, and satellite receivers are used to receive satellite signals for features such as GPS navigation.
