The international treaty specifically responsible for phasing out chlorofluorocarbons (CFCs) to protect the stratospheric ozone layer is:

• A Kyoto Protocol
• B Paris Agreement
• C Stockholm Convention
• D Montreal Protocol ✓

Explanation

The Montreal Protocol on Substances that Deplete the Ozone Layer (1987) mandates phased elimination of CFCs, halons and other ozone-depleting chemicals, and is widely regarded as the most successful environmental treaty. The Kyoto Protocol and Paris Agreement target greenhouse gases and climate change, not ozone. The Stockholm Convention addresses persistent organic pollutants such as DDT and dioxins.
