What qualifies as an "ozone-depleting substance"?

The correct answer identifies an "ozone-depleting substance" as any chemical that can harm the ozone layer. This includes a variety of synthetic chemicals, particularly chlorofluorocarbons (CFCs), halons, and other related compounds that have been shown to have a detrimental impact on the ozone layer. These substances work by releasing chlorine or bromine when they are broken down in the atmosphere, which then catalyzes the destruction of ozone molecules. Protecting the ozone layer is vital because it shields the Earth from harmful ultraviolet (UV) radiation.

The other choices are too specific or misleading. High global warming potential is relevant for climate change but does not encompass all ozone-depleting substances, as some may not contribute significantly to global warming. Not all substances used in automotive maintenance qualify, as many do not have the properties to affect the ozone layer. Similarly, while some household cleaners can contain ozone-depleting substances, it is not accurate to categorize all substances found in them as such; this group is too broad and lacks specificity.
