Answer: C. Citizens of individual states were also citizens of the United States.
The Articles of Confederation was an agreement between the thirteen colonies that served as the first constitution of the United States.
This passage establishes the right of all citizens of the individual states to enjoy full citizenship rights in all the other states of the union. However, it excludes paupers, vagabonds and fugitives of justice, as they do not enjoy the same rights as the general population even in their own colony.
