Explanation:

The Spanish-American War (1898) resulted in the U.S. acquiring territories like Puerto Rico, Guam, and the Philippines, expanding its influence into Asia and the Americas. This expansion marked its transition from a regional to a global power with an extended overseas presence. Other options are incorrect: British power was not directly threatened by this specific expansion; China/Japan’s port openings predate the war; Spain lost colonial power, not gained it in Europe.

Answer:

D. became a worldwide power with an extended empire.
