i will medal if correct

The correct answer is C. the Vietcong could strike any major city in South Vietnam

Explanation:

The Tet Offensive of 1968 was a military campaign or operation during the Vietnam War during this campaign the Viet Cong (National Liberation Front) and People from North Vietnam fought against the South Vietnamese Army and the United States, this resulted in the Viet Cong and North Vietnamese striking around 100 towns and cities throughout Vietnam despite  the South Vietnamese Army, the U.S, and other allies had prepared defensive strategies, because of this, the results were surprising for the Vietnamese Army as they lost control (temporarily) of the cities and towns stricken and this showed the Vietcong could strike any major city in South Vietnam.
