Correct Answer: Antarctica

Solution : The correct option is Antarctica .

The ozone hole is a region in the Earth's stratosphere where the concentration of ozone (O ₃ ) is significantly reduced. This thinning of the ozone layer primarily occurs over Antarctica and is most prominent during the Southern Hemisphere's spring (September to November). The ozone hole is a human-made environmental issue and is caused by the release of man-made chemicals, primarily chlorofluorocarbons (CFCs), into the atmosphere. These chemicals break down ozone molecules.
