Answer:
Correct answer is B. The League of Nations
Step-by-step explanation:
Treaty of Versailles was signed after WW1. Losing countries, especially Germany were not satisfied with the treatment they received at the Conference. The decisions provoked Germans after the war, and that is why options C and D are not correct.
