Answer:
b. also known in the United States as the Viet Cong.
Step-by-step explanation:
The National Liberation Front (NLF), was originally formed by the North Veitnam as the National Front for the Liberation of the South for the purpose of achieving similar success of Viet Minh, the total nationalist organization that successfully liberated Vietnam from French colonial rule.
However, the United States generally considered the NLF the “Viet Cong,” a short version of Viet Nam Cong San which translates to Vietnamese Communists.
