The correct answer is C. The League of Nations could not take direct action against Italy.
The League of Nations, established after World War I to promote peace and cooperation, faced significant challenges and limitations in its ability to respond to aggressive acts by member states. In the case of the Italian invasion of Ethiopia in 1935, while the League condemned the invasion and imposed some sanctions on Italy, these measures were insufficient to stop the aggression, and the League ultimately lacked the resolve or capability to enforce its decisions effectively.
