What characteristic of CFC refrigerants makes them more likely to reach the stratosphere than most other compounds that contain chlorine?
A. CFCs are attracted to the dust in the stratosphere
B. CFCs are attracted to the static in the stratosphere
C. CFCs that contain chlorine but not hydrogen are so stable that they do not break down in the lower atmosphere
D. CFCs are lighter than other damaging compounds making them easier to float upward when released
Answer (2)
CFCs are more likely to reach the stratosphere because they are highly stable and do not break down in the lower atmosphere. This stability allows them to survive long enough to ascend to the stratosphere, where they can release harmful chlorine atoms. Therefore, the correct answer is option C.

CFCs are more likely to reach the stratosphere due to their exceptional stability, which allows them to avoid breakdown in the lower atmosphere. Unlike other chlorine-containing compounds that often decompose, CFCs persist long enough to ascend. Thus, their stability is significant in contributing to ozone depletion. ;
