Solution

The correct option is B Circuit switched

A telephone network is an example of Circuit switched network.

Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. ... The defining example of a circuit-switched network is the early analog telephone network.

An example of a circuit-switched network is an analog telephone network. ... They do not establish a dedicated communications channel between hosts, rather they offer a “best effort” network that can be used by a variety of hosts to communicate at the same time.

Circuit switching is the most familiar technique used to build a communications network. It is used for ordinary telephone calls. It allows communications equipment and circuits, to be shared among users. Each user has sole access to a circuit (functionally equivalent to a pair of copper wires) during network use.

Packet switching and circuit switching are two networking methods for transferring data between two nodes or hosts. For a packet-switched network, data is transferred by dividing the data into individual packets and passing it through the circuits to the other host.
