Which statement indicates an inappropriate tone in a message asking for clarification?

The statement that reflects an inappropriate tone is one that carries an assumption or inadvertently suggests a lack of understanding or knowledge. In this case, the wording can come across as slightly accusatory or dismissive, particularly if the phrasing implies that the sender is skeptical about the information provided.

The choice in question poses a direct question that suggests disbelief or confusion but is framed in a way that could be interpreted as questioning the other person's ability to communicate clearly. Good communication, especially when seeking clarification, should be neutral and open-ended, inviting additional information without implying that the other person's statement was unclear or erroneous.

In contrast, the other options maintain a polite and constructive tone. They express gratitude, offer assistance, or simply request clarification in a respectful manner, which fosters a more positive exchange of information. This helps to establish a collaborative dialogue rather than one that could lead to defensiveness or misunderstanding.
