What role did colonial peoples have in World War I? Which option is correct

Because they lived far from where the war was in Europe, they did not have much direct experience with it.

Although a few people in the colonies fought in the war, this had little impact on the colonies.

European empires did not want to use colonial people in the war because they were not European.

They were often required to serve in militaries or provide labor for European nations engaged in the conflict.
