Final answer:
The Declaration of Independence has partially lived up to its promises by establishing democratic principles, but has faced contradictions, particularly regarding slavery and economic freedom. So the correct option is B.
Step-by-step explanation:
Whether the Declaration of Independence has lived up to its promises today is a complex issue and can be seen as partially achieved. The Declaration, anchored in Enlightenment principles, proclaims ideals such as sovereignty, natural rights, and the social contract. While the creation of the United States represented a monumental shift towards these ideals, and set a precedent for future democratic movements, the reality was that not all individuals experienced freedom and equality during the founding era. Historian Gary B. Nash's observation highlights the paradox of the era, with political liberty coexisting with the institution of slavery. The Declaration of Independence has had a global impact and is considered one of the most important documents in American history. Engaging with its complex legacy involves acknowledging both its profound influence and the struggles to live up to its promises fully, particularly regarding economic freedom and equality for all citizens.
