How did vietnamization lead to the end of the war? a) north vietnam ran out of funds b) us troops surrendered c) south vietnam fell d) president nixon declared victory

 C) South Vietnam fell

President Nixon’s Vietnamization policy emphasized that the United States must empower South Vietnamese forces to assume more combat duties.

By the time the US was shifting emphasis to this sort of policy, it was too late to stave off the victory of the North Vietnamese and Viet Cong forces.  The US eventually withdrew its forces from Vietnam in 1973, and by 1975, Saigon (in South Vietnam) fell to the North Vietnamese communist forces..

this isn't a question and if you're going to list things be kind and use commas.
