The correct answer is C. All US troops had left South Vietnam by the end of March of 1973.
On March 29, 1973, two months after the signing of the peace agreement in Paris, the last American combat troops were leaving South Vietnam, and the prisoners of war captured in North Vietnam were released. The eight years of American intervention in the Vietnam War had ended, with the United States being defeated.
