Which of the following additional sentences would work best at the end of this passage if it were an advertisement for a school or college?

Answer choice (D) is correct because it is an accurate call to action for an advertisement that a school is running. Answer choice (C) might be tempting, but it would work fine with the passage as it is now and offers nothing new that relates to an advertisement for a school or college. Answer choices (A) and (B) would be less effective than the correct answer because they are too specific and not specific enough, respectively.
