Quizplus · Accepted Answer

The main man-made cause of ozone depletion in the stratosphere is the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances, which contain chlorine and bromine. Once released, these chemicals can reach the stratosphere, where they react with ozone and break it down into oxygen, leading to the depletion of the ozone layer. Therefore, the correct answer is D, which represents chlorine, a chemical component of CFCs that is responsible for the majority of ozone depletion.
