The best answer would be D.
The debate over whether a bill of rights should be added to the Constitution or not, started from some delegates' beliefs that guarantees of certain basic rights were missing from the ratified Constitution. They wanted some amendments to be included, in order to secure those liberties to the citizens.
The Federalists (those who supported the ratification of the Constitution) argued that the Constitution did not need a bill of rights because the people and the states kept any powers not given to the federal gonvernmnet. Alexander Hamilton, for example, argued that because the proposed federal government would possess only specifically assigned limited powers, ir could not threaten the fundamental liberties of the people. Anti-Federalists, however, held that a bill of rights was necessary to safeguard individual liberty and the power of the states.
