The function of multiplexing is

a.) To reduce the bandwidth of the signal to be transmitted
b.) To combine multiple data streams over a single data channel
c.) To allow multiple data streams over multiple channels in a prescribed format
d.) To match the frequencies of the signal at the transmitter as well as the receiver.

Correct Answer: To combine multiple data streams over a single data channel

Explanation:

Multiplexing is a process where multiple data streams from different sources are combined and transmitted over a single data channel. Multiplexer or MUX is placed at the transmitting end to combine the signals and a De multiplexer or DEMUX is placed at the receiver that separates the received signals and sends them to their corresponding destinations.

Multiplexing techniques are classified as Time-division multiplexing (TDM) and Frequency-division multiplexing (FDM).
