a. public opposition to the vietnam war had made him unpopular.
b. public support for the vietnam war had made him unpopular.
c. he had already served two terms as us president.
d. his speech at the democratic national convention had prompted violence.

The correct answer is A, as he decided not to run for reelection in 1968 because of the public opposition to the Vietnam War that had made him unpopular.

In 1964, President Lyndon B. Johnson had defeated Republican Barry Goldwater for the most crushing majority seen until then. By 1968, however, his image had deteriorated badly: His achievements with his plan for "The Great Society" and the "space race" were overshadowed by numerous race riots throughout the country after the passage of the Civil Rights Act. . The rise of hippie movements, the "New Left" and black militant organizations led to an important polarization between classes, generations and races.

However, it was the Vietcong conflict that had hit the head of state the most: By the end of 1967, there were 500,000 Americans in Vietnam, with about a thousand fallen per month, most of them recruits. At the beginning of 1968, the minister Robert McNamara announced an imminent end of the hostilities to the smaller intensity of combat on the part of the North Vietnamese. Soon after, Hanoi launched the Tet Offensive, which devastated all of South Vietnam. After the attacks, the approval of Johnson only reached 35%, which caused serious doubts about his future in the Oval Hall.
