Answer:
The correct answer is A. Most nations from World War I were not members of the League of Nations.
Step-by-step explanation:
The League of Nations was an international body created in 1920, in the aftermath of World War I with the aim of establishing peace in the world. Its founding document was incorporated in the peace treaties made after the Great War, but the United States refused to accept the Treaty of Versailles and was consequently expelled from the League. This hindered the work of the organization from the outset. Nevertheless, the Alliance did important work in resolving disputes, organizing international congresses on several topics and carrying out humanitarian work. However, the League failed to deal with the developing international situation in the thirties, such as the Japanese war in China, Italy in Ethiopia and most of all the German cause, which withdrew from the League in 1933.
