Halon and cfc's both a) inhibit ozone formation b) cause ozone formation in the troposphere c) destroy ozone in the stratosphere d) causes excess ozone formation in the stratosphere

C) Haloalkanes (Halons) and Chloroflurocarbons (CFS's) are chemical gases that may be carried into the stratosphere, where the ozone layer resides. These chemicals react with ozone and cause a reaction that breaks ozone down into oxygen. Depletion of the ozone layer causes an increase in the ultraviolet radiation entering the earth.
