C) He gives examples of denied citizenship rights.
Explanation:
Dr. King states that Black people in America do not enjoy the freedoms they are meant to enjoy (granted by the Constitution). They also do not enjoy full citizenship. In order to show how this is the case, Dr. King gives examples of denied citizenship rights. Jim Crow laws in particular were very restrictive of rights for African Americans. They did not allow them to move freely, study in the school they desired or marry the person they loved.
