Answer: С: The Great Compromise was declared unconstitutional
Explanation:
The Dred Scott decision has been denounced as one of the worst by the nation's Supreme Court because it established that enslaved people were property and hence could not be American citizens. Southerners loved this decision as it enforced their view on slavery and with the striking down of the Missouri Compromise, slavery was allowed into the new territories.
This decision did not affect the Great Compromise of 1787 that enabled the creation of the bicameral Congressional format that the United States began to follow for its legislature that created both the Senate and the House of Representatives.
