Answer:
B. Significance
Step-by-step explanation:
The emotional connotation of the underlined word helps King emphasize the document's significance. The document's significance is emotional, and it makes the audience feel as if they are in a dream. It was an emotional daybreak for black slaves.
It removed the legal stigma from slavery and made it possible for blacks to vote in the South after Reconstruction ended. This proclamation is called "the most powerful statement" because it not only declared freedom to black slaves, but also stated that all people were equal under God. It defined equality as something that could be achieved by working hard and being educated, which meant many white Southerners felt they were losing their jobs and property because of blacks' new right to vote.
