B. Ohio is the U.S. state that is NOT separated from Canada by a natural border. The other states listed (Michigan, North Dakota, and Pennsylvania) have natural borders with Canada, such as rivers and lakes. Ohio shares a border with Canada at Lake Erie but does not have a natural border that defines the boundary with Canada.
