Option C

Explanation:

American imperialism dated back to nineteenth-century when the US and the other powerful countries want to expand their control over military, economic and other possessions. Many people were in favour of this while others were not.

As this law makes the US competitive in regards to the economic background with other countries, some people supported imperialism. While the others thought that it would violate America's anti-colonial principles. Government legitimacy and moral rights will be abandoned by this imperialism and it would hinder the republication of the American government.
