Which of the following is an example of a reflective statement?

A reflective statement is designed to indicate that the speaker is processing or considering the information provided by another person. In this context, the phrase "I see" demonstrates acknowledgment and understanding of another individual’s perspective or feelings. This type of statement invites further communication and allows the speaker to convey that they are actively engaged in the conversation.

The other options, while potentially useful in various conversations, do not convey the same level of active engagement and reflection. "This is challenging" expresses the speaker's own evaluation of a situation rather than reflecting on someone else's thoughts. "Why do you think that is?" poses a question but does not necessarily reflect or affirm the other person's viewpoint. "Let's move on" indicates a desire to change the subject rather than engage with what has been discussed. Thus, the phrase "I see" stands out as the most reflective statement among the choices provided.
