The correct answer is B. they thought the people's liberties needed protection from the government; increase individual rights.
The Anti-federalist were a group of individuals who feared that the new US Constitution would give the federal government too much power. This power could then be used to limit the rights of American citizens. This fear is rooted in America's experience as colonies underneath British control.
To prevent this type of situation from happening, the Anti-federalist proposed a Bill of Rights. This would be a list of rights and liberties that all American citizens possessed. These rights would never be allowed to be taken away by the government.
