In the Shannon–Weaver model, the channel is the pathway or medium that carries the encoded signal from transmitter to receiver. Examples include telephone wires, air for spoken sound waves, or fibre optics for digital signals. The choice and quality of the channel influence how much noise affects the signal and thus how accurately the receiver can reconstruct the message. Channel is therefore a structural component of the transmission process.

Option A:
Option A incorrectly identifies the sender as the channel. The person who initiates the message is the source, not the pathway it travels through.

Option B:
Option B, the physical medium carrying the signal, matches the definition of channel in this model. It highlights that the channel is distinct from both source and receiver but essential for moving information between them.

Option C:
Option C refers to the ideas and thoughts in the sender’s mind, which form the content of the message or information source, not the channel used for transmission.

Option D:
Option D, the feedback given by the receiver, is the response to the message. Feedback is a separate element of the communication process and, in the original Shannon–Weaver model, is not treated as the channel.

Every communication event begins when someone decides to express an idea, instruction or feeling. In a classroom, this initiator is often the teacher, though students can also take that role. The person who formulates and encodes the message into words, symbols or gestures is called the sender.

Option A:
Sender is the correct term for the originator of the message who encodes ideas for transmission. In classroom contexts, teachers as senders select content and language that they hope students will understand.

Option B:
Receiver is the person or group for whom the message is intended, usually students in a teaching situation. They decode rather than initiate the message.

Option C:
Channel refers to the medium through which the message travels, such as speech, writing or electronic media, not the person initiating the message.

Option D:
Feedback is the response given by the receiver back to the sender, indicating how the message has been interpreted, rather than the origin of the message.
