The Tools by Which Modern Presidential Administrations Control Their Image

The tools by which modern presidential administrations control their image include all of the following EXCEPT

A) calling on members of the press corps who are known to throw out softball questions.
B) giving low-level members of the administration wide latitude to interact with the press and offer various, even competing, explanations of the president's policies.
C) issuing frequent press releases, which clearly enunciate the reasoning behind presidential policy.
D) floating "trial balloons" to test the public response to an issue before making a wholehearted commitment about it.
E) briefing of the president on potential questions before a conference, and limiting reporters to only one follow-up question.
