What is a synonym for feedback?

A synonym for feedback is "response" because it captures the essence of feedback as a reply to an action, question, or situation. Feedback is often given in reaction to something that has occurred, serving the purpose of providing information about that action, which aligns with the definition of a response.

The other choices do not adequately reflect the meaning of feedback. A symbol represents an idea or concept rather than providing a reply or evaluation. A verbal answer refers specifically to spoken communication, which may not encompass all forms of feedback. Nonverbal reaction may convey some intention or message but does not explicitly align with the interactive component of providing feedback in the context of a discussion or evaluation.
