• A. ARVN
• B. Viet Minh
• C. PRG
• D. Saigon Government

Answer: (C)

Think of it as the insurgents’ bid for political legitimacy alongside their military campaign. On June 8, 1969, the Provisional Revolutionary Government of the Republic of South Vietnam was formed as an underground administration representing the Viet Cong and North Vietnamese aims in the South. It was designed to be the legitimate, alternative government to the Saigon-based regime, claiming authority over South Vietnam and even taking part in international diplomacy as the insurgent’s representative. This is why it fits the description of an underground government opposing the South Vietnamese government. The other names refer to groups or regimes tied to different roles—ARVN as the South Vietnamese army, Viet Minh as the earlier independence movement, and the Saigon Government as the government the PRG opposed.
