For a Majority of Northerners, the MOST Outrageous Part of the Several

For a majority of northerners, the MOST outrageous part of the several objectionable parts of the U.S. Supreme Court Chief Justice Roger Taney's majority opinion (decision) in the Dred Scott case was that the Court ruled that

A) the Constitution could not be amended to prohibit slavery because that such an amendment would violate Americans' Fifth Amendment property rights.
B) Scott did not automatically become free when his owner took him through free states and territories.
C) Congress never had the constitutional power to prohibit slavery in any territory.
D) black slaves did not have the constitutional power to sue in federal courts to win their freedom.
E) the Bill of Rights did not apply even to free African Americans.
