Which statement best describes the impact of 20th-century conflict such as world war 1 and world war 2?

D.

Explanation:

The most accurate answer is that these conflicts contributed to other ones by failing to resolve important issues. Some of the issues that were not solved by the war was the status of Germany, the independence of colonial regions, or the protection of human rights. However, the other options are incorrect as the wars influenced the whole world (not just a region), usually resulted in less colonial holdings, rather than more and increased the interest in the protection of human rights.
