Question
From monitoring stations around the globe, data was collected to produce the above graphs. These graphs show atmospheric concentrations of several halogenated gases (gases that contain fluorine, chlorine, or bromine), measured in parts per trillion (ppt). What is the atom or element that is present in all of the compounds in the left-hand graph which causes them to be ozone-depleting substances?

The correct answer is **C: Chlorine.**
Chlorine is a key element in many ozone-depleting substances, such as chlorofluorocarbons (CFCs), which are known to contribute to the depletion of the ozone layer. While bromine and fluorine can also be found in halogenated ozone-depleting substances, the question specifically asks for the common element present in all compounds in the left-hand graph that leads to ozone depletion, which would likely refer primarily to chlorine compounds.
