The most accurate statement regarding how Manifest Destiny was affected by the Mexican-American War is:

**The United States achieved its Manifest Destiny goal of owning territory from the Atlantic to the Pacific Ocean.**

The Mexican-American War (1846-1848) resulted in significant territorial gains for the United States, including present-day California, Nevada, Utah, Arizona, and parts of Colorado and New Mexico. This expansion was seen as a fulfillment of the Manifest Destiny ideology, which held that the U.S. was destined to expand across the continent. The war not only solidified U.S. territory from coast to coast but also intensified discussions about the implications of such expansion, particularly regarding slavery and relations with Native Americans.
