Feedback in two way communication – UGC NET Question

Two-way communication requires a loop in which the receiver responds to the sender. This return message tells the sender whether the original message was received and understood. In communication theory,this response is known as feedback. Thus,the stem correctly points to feedback as the key element.

Option A:
Feedback closes the communication loop by informing the sender about the effectiveness of the message. It may be verbal,non verbal or written,but in every case it functions as a response. Because the stem emphasises this return message,feedback is the correct option.

Option B:
Redundancy refers to deliberate repetition of information to make the message clearer or more robust. It is not the name for the receiver’s response to the sender. So it does not answer the question.

Option C:
Encoding is the sender’s act of translating ideas into symbols before sending the message. It occurs before the receiver responds and therefore cannot refer to the response itself.

Option D:
Gatekeeping relates to control over which messages are allowed to pass through a channel,such as an editor choosing news items. It is not the feedback process between sender and receiver.
