yes it is
I don't agree with A. Following this procedure how would you name AlCl3? Trichloroaluminum something. I would name it aluminum chloride. Doesn't the cation always go first? What about K2SO4. Do you name that sulfatosomethngdipotassium. I see a lot of this potassium tetraoxosulfate(VI) but that is not an IUPAC accepted name.
