October 2
Correct Answer: B
Detailed Solution
Every year, 16 September is observed as the International Day for the Preservation of the Ozone Layer, commonly known as World Ozone Day. The United Nations officially identifies 16 September as the date of this observance.
The date commemorates the Montreal Protocol on Substances that Deplete the Ozone Layer, which was signed on 16 September 1987. The Protocol was designed to control and phase out the production and consumption of Ozone-Depleting Substances (ODS).
In 1994, the United Nations General Assembly, through Resolution 49/114, proclaimed 16 September as the International Day for the Preservation of the Ozone Layer. Its observance began in 1995.
The Ozone Layer is an Ozone-rich region mainly in the Stratosphere and protects life on Earth by absorbing much of the harmful Ultraviolet radiation coming from the Sun. Approximately 90% of atmospheric Ozone occurs in the Stratosphere.
16 September 1987 → Montreal Protocol signed
