World Ozone Day is observed on which date?
- A.5 September
- B.16 September
- C.16 October
- D.5 June
Correct answer
Explanation
The correct answer is B, 16 September. The day, formally the International Day for the Preservation of the Ozone Layer, marks the signing of the Montreal Protocol on 16 September 1987, the agreement under which countries agreed to stop using chlorofluorocarbons and other substances that thin the ozone layer.
Option A, 5 September, is Teachers' Day in India. Option C, 16 October, is World Food Day, which marks the founding of the Food and Agriculture Organization in 1945, and the matching day of the month makes it the strongest distractor here. Option D, 5 June, is World Environment Day, which is about the environment as a whole and is set by the United Nations Environment Programme, not by the Montreal Protocol. Learning each of these four dates with the reason behind it is the only safe way to keep them apart in the examination hall.
