The correct answer is letter C.
Explanation: The Articles of Confederation and the Perpetual Union, known as the Articles of Confederation, constituted the first document of Government of the United States of America. These important points were approved by the Second Continental Congress, which took place on 1777, after several months of debate.
Conversations between the Representatives of the Colonies resulted in a non-binding guideline until its ratification four years later, on 1 March 1781. The Articles of Confederation are considered one of the four founding documents of the American nation.
