The correct answer is - C. ''Let's put the story about the governor's gambling addiction on the front page'' - everyone will buy today's edition.
The sensationalism is a method that is very often used by the media in order to get more attention and higher sales, thus higher profits. Most of the times the news wouldn't even be that important, but the title that is going to be put on the news will provoke and attract the people to read it because it looks very interesting and it triggers the human brain to find out more.
The example about the governor's gambling addiction is a nice example for this type of method. The news is not really that important, and its content may be very poor or lacking proof, but the people will be automatically attracted to the sensational title, thus buying that particular edition.
