The correct answer is C. Silent Majority.
With all of the anti-war protests taking place around the US during the late 1960's and early 1970's, Nixon looked to a specific group to show support for the US's efforts in Vietnam. He named this group the silent majority. His argument was that most American citizens still supported the US cause of stopping the spread of communism from North Vietnam to South Vietnam. However, he said that because these individuals are not out protesting or being active, they are not covered by the media.
