The correct response is: The United States acquired Spanish territories in the Caribbean Sea and in the Pacific Ocean.
This acquisition of territories, following the Spanish-American War in 1898, marked a significant expansion of U.S. influence and presence on the global stage, contributing to its emergence as a world power. The war resulted in the United States gaining control over territories such as Puerto Rico, Guam, and the Philippines, thus extending its reach beyond continental borders and into international affairs.
