The correct answer to this question would be C. Benjaming Banneker was a free African American who lived during the time when the principles stated in the Declaration of Independence and the Bill of Rights were leading the way of acting and thinking of the American society. However, despite all the freedoms and rights acquired by the American people, African Americans and all freed slaves were not enjoying the effects of these principles. Thus, Benjamin Banneker wrote to a public letter to Thomas Jefferson, the U.S President at the time, challenging the way that Jefferson was not enforcing the rights and liberties established by both the Bill of Rights and Declaration of Independence in benefit of black people in general. What Banneker did, was remind Jefferson of the beliefs that he himself had on the equality of all men established by God and that were so much a part of the Bill of Rights and Declaration of Independence.
