This question is tough to answer, since perceptions of Manifest Destiny changed radically across the 19th century.
But many American citizens, politicians, and thinkers genuinely believed in the tenets of Manifest Destiny, so it's not fair to say that these Americans were simply manufacturing a false excuse for westward expansion. So we can exclude C.
It's also true that many other Americans (especially Southern Democrats) used the idea of Manifest Destiny to justify invading Mexico in the 1840s. Bu these Southerners were more interested in adding new slaveholding states to the Union than they were with fending off a potential enemy in Mexico (which was a vastly weaker military power).
And while much of America throughout the 19th century was indeed Protestant, and that most of the residents of Mexican territories were Catholic, Manifest Destiny was less interested in dismantling Catholic influence than it was in advancing its own expansionist, Protestant interests.
You'll want to double-check with your textbook to be sure about the context of this question, but the best answer from this angle seems to be B, since those Americans who did believe in Manifest Destiny certainly believed that westward advancement was not only obvious but sanctioned by God.

The colonists felt nothing but resentment about the Navigation Acts. The Navigation Acts limited their trade with nations other than England.
The establishment of electric utilities led to widespread use of electricity in the United States.
<u>Explanation:</u>
Electricity was not used only to power homes but also factories and industries. This eventually enabled factories and industries to make use of large and sophisticated machines that could help in increasing the efficiency and productivity of the factories.
This enhanced the industrial revolution which was already taking place in the United States.With electricity, workdays and work time increased which led to increased production and thereby led to the boost in the economy of the United States.
An important benefit of the laissez-faire policies of the federal government in the late 19th century is that many American industries, such as railroads, steel and oil, achieved rapid growth.
Industrial expansion accelerated during and after the Civil War. During the Civil War the Union Congress approved bond issues and land grants to finance the construction of the transcontinental railroad by the Central Pacific and Union Pacific railroads. The railroad connected California with the Midwest, and made protected, all-weather coast-to-coast rail travel and transport economically feasible.
