Many Americans viewed the Mexican Cession as a success primarily because of reason
C: it completed America's expansion to the Pacific Ocean. This was significant as it fulfilled the idea of Manifest Destiny, the belief that the United States was destined to expand across the North American continent from the Atlantic to the Pacific Ocean. It provided the United States with vast new territories that could be settled by Americans and used for various economic activities like agriculture and mining.
