Answer & Solution
Correct answer: C. The phenomenon increased the global mean sea level by several inches during the past century
Rising sea level is attributed to global warming, not ozone depletion. Ozone depletion is caused by chlorine and bromine compounds (CFCs, halons), allowed more UV to reach Earth, and was detected at around 5% reduction between 1979 and 1990.
