25th December

Correct Answer: C
Detailed Solution
Every year, 16 September is observed as World Ozone Day. Its official name is the International Day for the Preservation of the Ozone Layer.
The date is associated with the Montreal Protocol on Substances that Deplete the Ozone Layer, which was adopted on 16 September 1987.
In 1994, the United Nations General Assembly proclaimed 16 September as the International Day for the Preservation of the Ozone Layer.
The Ozone Layer is located mainly in the stratosphere. It protects life on Earth by absorbing a large proportion of harmful Ultraviolet-B (UV-B) radiation coming from the Sun.
CFCs, halons and other ozone-depleting substances (ODS) can damage stratospheric ozone. The Montreal Protocol primarily aims at phasing out the production and consumption of such substances.
