President McKinley justified American acquisition of the Philippines primarily by emphasizing that

a. the Filipinos wanted to be annexed by the United States
b. the electoral success of the Republican party depended on their acquisition
c. there was no acceptable alternative to their acquisition
d. the Philippines were spoils of war and America's by right of conquest

i think that it is not B but i have no idea the right answer

Since this is not my area of expertise, I searched Google under the key words "McKinley Philippines" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.

To determine the correct answer, we can analyze the reasons given by President McKinley for justifying the American acquisition of the Philippines. One way to do this is to examine primary sources such as speeches or official statements made by McKinley during that time.

As President McKinley stated in his official statement on December 21, 1898, one of the key justifications for acquiring the Philippines was that there was no acceptable alternative to their acquisition. This aligns with option c.

However, it is important to note that McKinley's justification also included elements of option a. While it is true that not all Filipinos wanted to be annexed by the United States, McKinley argued that the United States had a duty to "uplift and civilize" the Filipino people, thereby suggesting that annexation would be beneficial for them.

It is also worth mentioning that option d may be partly accurate, as McKinley referred to the Philippines as "the spoils of war" but did not explicitly emphasize "right of conquest" as the primary justification.

Given this information, the most appropriate answer appears to be:

c. there was no acceptable alternative to their acquisition
