Final answer:
World War I led to increased colonial autonomy and demands for self-determination as colonies contributed to the war effort and began to seek greater recognition and rights, resulting in the growth of nationalist movements. Hence, the correct answer is option B.
Step-by-step explanation:
The correct answer is B) It led to increased colonial autonomy and demands for self-determination.
World War I had a significant impact on the relationship between the mother countries and their colonies. The war weakened the mother countries and exposed their vulnerabilities, leading to increased demands for self-determination and independence from the colonies. Many colonies saw an opportunity to assert their own autonomy as the mother countries were occupied with the war.
Examples of the impact of World War I on colonies include the rise of nationalist movements in India and Egypt, which eventually led to their independence from British rule, and the demand for self-governance in West Africa, leading to the creation of new African states.
