Answer:
B. Missouri Compromise; 5th
Explanation:
In 1854, the Missouri Compromise was repealed by the Kansas-Nebraska Act and three years after that, the Missouri Compromise was declared unconstitutional by the Supreme Court in the Dred Scott decision.
It is the 5th amendment that protects the right of property whereas the 6th amendment protects the rights of criminal defendants. Because of this I would say that B is the best choice. Hope this helps and let me know if you have questions!
