Option C. What convinced the United States to join the United Nations is that both political parties, and the public, agreed that it would help prevent future world wars.

Explanation:

As the text shows, The Senate of the United States, after a congressional debate, officially approved the UN Charter on July 28, 1945, and with its approval a historic moment for the United States and for international cooperation was settled. The main reason that convinced the United States' Congress as well as the public opinion, that the country should join the United Nations was that a majority believed that the organization would help prevent future wars, and that it was important to learn from the mistakes made previously, with the League of Nations, when after the Senate debated whether or not the country should participate in the organization, it was voted that it shouldn't and then a major agent such as the United States was not a part of an international organization that had the goal to maintain world peace.
