Which of the following elements is part of feedback in communication?

Feedback in communication is essential because it allows the sender to understand how their message was received. The response to the message directly illustrates this feedback process. When the receiver offers a response, whether verbal or non-verbal, it provides the sender with information about the effectiveness of their communication. This response can indicate whether the message was understood, accepted, or if further clarification is needed, thereby completing the communication loop.

In other contexts, while aspects like the sender's educational background, the receiver's emotional state, and the sender's tone of voice can influence communication, they do not constitute feedback on their own. They can affect the delivery and perception of the message but do not fulfill the role of response, which is critical for effective communication. The receiver's feedback serves as a direct interactive component that validates or challenges the initial message, making it a fundamental element of successful communication.
