Which one of the following is associated with the issue of control and phasing out of the use of ozone-depleting substances?

The correct option is Montreal Protocol.

The Montreal Protocol on Substances that Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production and consumption of numerous substances that are responsible for ozone depletion.
Signed on September 16, 1987, and entering into force on January 1, 1989, it is widely considered one of the most successful environmental agreements in history.

To understand why this option is correct, we can look at the scope of each protocol/conference listed:
1. Montreal Protocol: Specifically targets the control and phasing out of Ozone-Depleting Substances (ODS) such as chlorofluorocarbons (CFCs) and halons.
2. Bretton Woods Conference: Formally known as the United Nations Monetary and Financial Conference (1944), it was gathered to regulate the international monetary and financial order after World War II, leading to the creation of the IMF and the World Bank.
3. Kyoto Protocol: An international treaty that extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions to fight global warming.
4. Nagoya Protocol: A 2010 supplementary agreement to the Convention on Biological Diversity (CBD) focusing on access to genetic resources and the fair and equitable sharing of benefits arising from their utilization.

Therefore, the Montreal Protocol is the agreement directly associated with addressing the issue of ozone-depleting substances.
