Which statement regarding the decreased level of stratospheric ozone is correct?

• Increased photosynthetic activity has been measured in the phytoplankton around Antarctica

• The largest decrease in the level of stratospheric ozone over the Arctic region occurs between January and April

• Although the Montreal Protocol led to a reduction in the use of CFCs, it will have little effect on stratospheric ozone levels in the long term

• There is no correlation between the incidence of cataracts and skin cancers and the lower level so stratospheric ozone

• The global crop yields of wheat, rice, and corn have increased since the reduction in CFC use
