B is the way to go. With the A version you have to pull more toilet paper towards you in order to get a good rip and then you have excess toilet paper hanging down, which, if you have cats, is a disaster waiting to happen.
With the better choice, option B, allows you to access the proper amount toilet paper much easier without leaving much, if any, excess toilet paper behind.
