Which of the following statements best captures John Quincy Adams's interpretation of South Carolina Senator John Calhoun's arguments in favor of slavery?

The correct answer is c. Manual, unskilled labor is degrading to white men and most suitable to men of African descent. Having people of African descent perform manual labor makes true equality possible among whites.

Explanation:

John Calhoun was a staunch supporter of the institutions of slavery and clearly believed in the supremacy of the White European race over African slaves.

He eloquently described in his speeches and pamphlets how slavery as an institution is necessary for a functioning society. He believed that by living under a master, African slaves had a better living standard, and as such, was a natural form of hierarchy.

He got his belief system instilled from a young age from his father and he was known as the cast-iron man due to his strong convictions. He is today, also know as the man who started the American civil war.
