What does the phrase "'Hear you!'" convey?

The phrase "'Hear you!'" conveys a sense of surprise or disbelief regarding what has just been communicated. It indicates that the speaker is expressing astonishment at the information or statement shared, suggesting that they find it hard to accept or believe the validity of the message. This reflects a moment of emotional reaction rather than a request for clarification or repetition.

The phrase contrasts with the other options, which represent different contexts. For instance, expressing a lack of understanding or requesting repetition would not convey the element of surprise or incredulity that "'Hear you!'" implies. Similarly, demonstrating complete understanding does not align with the notion of surprise; it suggests that the listener fully comprehends and accepts the information without doubt. Thus, the emphasis on disbelief makes this phrase particularly distinctive in this context.
