Can you openly carry a firearm in Ohio without a CCW permit?

In Ohio, open carry of firearms is legal without a CCW permit, as long as it is not explicitly prohibited in certain locations such as schools, government buildings, and certain businesses that declare themselves as gun-free zones. Option A is incorrect because while open carry is allowed, there are still specific locations where it is not allowed. Option B is incorrect because rural areas do not have different regulations regarding open carry. Option C is incorrect because open carry is not strictly prohibited in Ohio.
