Answer:
The correct answer is B. Manifest Destiny was the belief that the United States was meant to be extended to the Pacific Ocean.
Explanation:
The ideology of Manifest Destiny, whose predominance in American politics occurred especially during the 1800s, established that the United States was a nation whose destiny was to expand the guidelines of Western civilization throughout the North American continent, from the shores of the Atlantic to the Pacific. Thus, this doctrine encouraged the United States to acquire territories to the west, such as the Louisiana Purchase or the War against Mexico.
