Final answer:
The correct answer is option A) American Dream.
Step-by-step explanation:
James Truslow Adams is credited with popularizing the phrase American Dream, which symbolizes a vision of a life that is richer and fuller, brimming with opportunity for success and prosperity. According to Adams's 1931 definition, the American Dream is the ideal where "Life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement" regardless of social class or the circumstances of birth. In essence, it represents the idea that through hard work and perseverance, every individual has the chance to succeed.
In contrast, the concept of Manifest Destiny is associated with John O'Sullivan and refers to the 19th-century doctrine that the expansion of the United States across the North American continent was both justified and inevitable. While related to American ideals, Manifest Destiny specifically deals with territorial expansion and the nation's growth, rather than individual prosperity and opportunity. It is important not to confuse the two as Manifest Destiny applies more to collective national destiny rather than personal achievement and opportunity.
