[DyllonKazuo]

The CFC propellants used in aerosol cans are chemically inert gases. This inertness leads to problems with stratospheric ozone because
 
  A) inert gases do not travel far in the atmosphere, so they are likely to react before rising very high.
  B) inert gases are especially likely to react chemically with the atmosphere.
  C) inert gases can drift upward for great distances without being broken down by the atmosphere.
  D) inert gases are especially attracted to ozone due to the fact that ozone is so highly reactive.
  E) inert gases are especially attracted to other inert, or nonreactive, gases such as ozone.
