Answer:
A. coastal South Carolina
Explanation:
The sentiments expressed in the proclamation would have been most widely condemned by White residents of "COASTAL SOUTH CAROLINA"
The above statement is based on the fact that following the split of North and South Carolina, South Carolina was characterized by the extensive cultivation of cotton, rice, tobacco, and indigo plantations near the sea islands and the Low Country of the South Carolina area. .These plantations were worked by African slaves.
The sentiment expressed in the proclamation stated that "We hold these truths to be self-evident, that all men are created equal..."
Hence, the White residents of Coastal South Carolina would have most widely condemned the proclamation because they have a lot to lose. As they would lose their slaves if they act accordingly.
