Explanation / Answer
Answer A
To share same medium for voice and data, we can use Multiplexing technique. In this case we can use Frequecy Division Multiplexing (FDM). In this same medium either air or cable can be use to transmit at the same time. Here frequency is divided for multiple users in bands and these bands can be simulteneously tramsmitted and are seperated at receivers end.

Summary:
The microprocessor inside a computer is a single multipurpose chip that has revolutionized people's life, allowing them to use one machine to surf the web, check emails and keep track of finances. Now, researchers have pulled off the same feat for light in the quantum world by developing an optical chip that can process photons in an infinite number of ways.
