How do you ask "Do you have any questions?" in Thai?

The phrase "คุณมีคำถามไหม" (khun mee kham tham mai) translates directly to "Do you have any questions?" in Thai. This construction is effective for inquiring if someone has questions to ask, as it includes "คุณ" (khun), meaning "you," followed by "มี" (mee), which means "to have," and "คำถาม" (kham tham), meaning "questions." The concluding "ไหม" (mai) is used to turn the statement into a question.

The other options don't convey the same meaning. While "คุณเป็นใครบ้าง" (khun pen khrai bang) translates to "Who are you?" and "คุณรู้ไหม" (khun ru mai) means "Do you know?" the phrase "คุณต้องการอะไร" (khun tongkan arai) asks "What do you want?" None of these choices directly addresses the act of asking if someone has questions, making option A the correct and appropriate choice for the inquiry.
