The correct answer is letter D

The Vietnam War was a conflict between North Vietnam and South Vietnam, from 1959 to 1975. This conflict was motivated by ideological issues and had the intense participation of the American army from 1965 to 1973.

Lyndon Johnson came to the American presidency in 1964 and, for a year, his government studied the possibilities of direct involvement in the Vietnam War. The change in the United States' stance came about because of dissatisfaction with the South Vietnamese government's inability to fight communist troops.

The effective participation of the United States in the conflict occurred after the Gulf of Tonquim Incident in August 1964. In that incident, the American vessel USS Maddox was attacked twice by North Vietnamese torpedo boats. The attacks, never proven by the American navy, were used as a pretext for the approval of resolutions that allowed the sending of the American army to the Vietnamese war.
