The correct answer to the question is:
The Geneva Accords
Explanation:
1. The Geneva Accords were a set of agreements signed in 1954 in Geneva, Switzerland, that aimed to resolve the conflicts in Vietnam.
2. These accords effectively ended the First Indochina War between the French and the Vietminh, leading to the division of Vietnam at the 17th parallel into North and South Vietnam.
3. The Treaty of Saigon is not the correct answer as it was not the specific treaty that ended the fighting between the French and the Vietminh.
4. The Vietnamese Declaration of Independence is not the correct answer either, as it was a historical document declaring Vietnam's independence from France but not specifically related to the end of the conflict between the French and the Vietminh.
Therefore, the most appropriate and accurate answer to the question is "The Geneva Accords."
