Are background checks required for private firearm sales in Ohio?

In Ohio, background checks are not required for private firearm sales. This means that individuals can sell firearms to each other without conducting a background check or going through a licensed firearms dealer. Option A is incorrect because it states that background checks are required for all sales, which is not the case in Ohio. Option C and D are also incorrect because they specify that background checks are required for only certain types of firearms, which is also not true in Ohio. Overall, the correct answer is B because it accurately reflects the current laws and regulations in Ohio regarding background checks for private gun sales.
