Which country experienced the growth of a communist movement that challenged the ruling nationalist government in the years after World War I?

a. America

b. Great Britain

c. Ottoman Empire

d. China

is it c?

No, the correct answer is d. China.

To arrive at this answer, you can examine the options and eliminate the ones that are clearly irrelevant. In this case, options a. America and b. Great Britain can be eliminated because they did not experience the growth of a communist movement that challenged their nationalist governments after World War I.

Next, you will need to compare the remaining options, c. Ottoman Empire and d. China. The Ottoman Empire was in decline after World War I and was soon dissolved, while China witnessed the rise of the Chinese Communist Party (CCP) during this period. The CCP, led by figures such as Mao Zedong, challenged the ruling nationalist government, leading to the Chinese Civil War.

Therefore, based on the comparison between the remaining options, the correct answer is d. China.
