The _____ from the listener makes the speaker to understand whether the information is conveyed correctly.a.smileb.Responsec.Nod of the headd.Eye contact

The best answer from the options provided is b. Response.

Explanation:

The effectiveness of communication often hinges on feedback from the listener to the speaker. Among the choices given, a response serves as a direct indicator that the listener has received and understood the information being conveyed. While a smile, nod of the head, and eye contact can all indicate engagement or agreement, they do not specifically indicate understanding in the same way that a verbal or non-verbal response does. Responses can include questions, comments, or any form of acknowledgment that clarifies comprehension, making it essential for effective communication. Thus, the listener's response is critical in helping the speaker gauge whether their message has been successfully conveyed and understood.
