destiny favored

The correct answer is (3) acquiring Texas and California.

The doctrine of Manifest  Destiny was an ideology during the 19th century that expressed the belief that the United States of America was destined to expand its frontiers from the Atlantic Ocean to the Pacific Ocean. This belief was used to justify the acquisition of territory and it was based on the notion that the United States of America was responsible for the expansion of modern civilization and progress, with its technological and scientific developments, to new lands. Therefore, according to this perspective, the USA not only had the right to expand but it was a responsibility to do so in the name of progress. For these reasons, supporters of this doctrine agreed on acquiring Texas and California since eventually acquiring them was a natural step in order to fulfill the goal of achieving the Pacific Ocean and taking Western civilization to these lands.

During the 1840’s supporters of Manifest Destiny favored acquiring Texas and California.

Further Explanations:

Manifest Destiny was an idea coined in the United States during 1845 that laid emphasis on expanding the dominion and spread of capitalism and democracy in the Northern part of the American continent. The doctrine during that era conveyed the belief of the destined expansion of American States from the limits of the Atlantic Ocean to the frontier of the Pacific Ocean. The doctrine of annexation of new territories was justified by the manifest that, the expansion is just to introduce modernization and technological advancement. This theory supported him with a reason to acquire Texas and California without any resistance.  

Annexation of Texas into the United States was done in 1845 and was acknowledged to the American Union on 29th December 1845. During the annexation vast amount of citizens were slaves and because of it, the slaveholding region infiltrated the political climate of the realm.

The rapid expansion policies based on the manifest destiny were advocating the expansion of dominion and at the same time raising the issue of slavery which resulted in the upsurge of the Civil War.
