Hi,
-Shania Twain, Celine Dion, and Bryan Adams are all Canadian-born singers. They have achieved international fame and success in the music industry. While option a suggests they were part of the modernization of American musical celebrities, it is incorrect as they are Canadian. Option c, which states that they all won multiple Grammy awards, is also incorrect as not all of them have won multiple Grammy awards. Option d, which suggests they contribute to international music forums regularly, is not mentioned in the question and therefore cannot be confirmed. The correct answer is option b: they are all Canadian-born singers.
