正确答案：A
解析：M: What do you think we should do about the mistake?
W: Why not ask Betty? I think she is ready to help us. she is kind and smart.
Q: What does the woman mean?
四个选项中都提到了Betty，又有answer，mistake，error等词，可以推断，本对话的问题可能是关于某个错误，Betty的意见或者行为。男士问这个错误我们应该怎么解决。女士建议男士去问问Betty。由此可见，Betty可能了解问题的解决方法(She is kind and smart)。故正确答案应为A)。
