Feedback element in communication – UGC NET Question

Feedback is the information sent back from receiver to sender about how the message has been understood. In a classroom,students’ questions and responses indicate whether they have followed the explanation. Teachers use this information to clarify or proceed. The stem describes exactly this two-way element,so feedback is the correct term.

Option A:
Channel refers to the medium through which the message travels,such as spoken words or visual aids,and is not about students’ responses.

Option B:
Encoding is the sender’s process of translating ideas into symbols,performed mainly by the teacher when planning and delivering explanations.

Option C:
Noise consists of any interference that distorts the message,such as background sounds or distractions,rather than helpful responses.

Option D:
Feedback closes the communication loop and is essential for effective teaching,so option D accurately completes the statement.
