The right answer is: E. The vandals. They were a Germanic people of central Europe.

Americans grew
critical of the war because the Viet Cong were viewed as remaining strong.
The North Vietnamese Army together with the Vietcong launched a massive offensive
on South Vietnam during the holiday of Tet. 
Fighting erupted on various fronts including the capital of Saigon.  Even the U.S. Embassy breached by the
enemy.  Though the Communists were driven
out and suffered massive casualties, American public opinion turned against the
war and it resulted into the withdrawal of U.S. troops from South Vietnam.  This led the North to conquer the South
ending in a unified Vietnam under Communist rule for decades.
