Which country most accurately represents an example of the growth of anti-colonial sentiment after world war i?

The answer is B) India

The last rebellion of 1857 was brutally controlled by the British Army. However, after the First World War, it was apparent that the British Empire was weak, both politically and economically.

This was seen by many in India, the best time to launch an active Independence movement against the colonists. 

The struggle of the Indian people was seen by people all over the world, as a cry for Independence on self-rule.
