The correct answer is: "Experience has clearly shown that the existing process of law cannot overcome systematic and ingenious discrimination."

Explanation:

With this quotation, the author tries to explain that African American people always have suffered systematic and ingenious discrimination, despite the existing laws. Although the laws tended to protected African Americans, people did not stop discriminating because of their skin color.  

They actually had rights and laws which were protecting those right, the history showed us that these laws were not respected as they should be.
