It's showing that A is right and not C. All the discussions says C is the correct answer.

Hi @Joyce, This is a Bizarro Must Be True question. Therefore, the correct answer will be the one answer choice that is not necessarily true. The other discussion posts were explaining why (C) is true, not why (C) is correct. Answer choice (A) is the correct answer for this question. Answer choice (C) is incorrect because it is true. Hope this helps! Please let us know if you have any further questions.
