Solution

The correct option is C Duplex

A connection between two end points, either physical or logical, over which data may travel in both directions simultaneously is called Duplex.

The primary difference between three modes of transmission is that in a simplex mode of transmission the communication is unidirectional or one-way whereas, in the half duplex mode of transmission the communication is two-directional, but the channel is interchangeably used by the both the connected devices.

transmission of data in just one direction at a time. For example, a walkie-talkie is a half-duplex device because only one party can talk at a time. In contrast, a telephone is a full-duplex device because both parties can talk simultaneously.

In telecommunication, duplex communication means that both ends of the communication can send and receive signals at the same time. Full-duplex communication is the same thing. Half-duplex is also bidirectional communication but signals can only flow in one direction at a time.

Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data.
