Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The question asks to identify the international environmental agreement that specifically targets the protection of the ozone layer by phasing out the chemicals responsible for its depletion.

Step 3: Detailed Explanation:
\[\begin{array}{rl} \bullet & \text{(B) Montreal Protocol: The Montreal Protocol on Substances that Deplete the Ozone Layer (1987) is a landmark international treaty designed to protect the ozone layer by phasing out the production and consumption of numerous substances that are responsible for ozone depletion, such as chlorofluorocarbons (CFCs) and halons. It is widely considered one of the most successful environmental agreements ever.} \\ \bullet & \text{(A) Kyoto Protocol: This was an international treaty that committed state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring and that human-made CO\(_2\) emissions are driving it. Its focus was climate change, not ozone depletion.} \\ \bullet & \text{(C) Paris Agreement: This is a legally binding international treaty on climate change, adopted in 2015. Its goal is to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels. Its focus is climate change.} \\ \bullet & \text{(D) Geneva Protocol: This is a treaty prohibiting the use of chemical and biological weapons in international armed conflicts. It is unrelated to environmental issues.} \\ \end{array}\]

Step 4: Final Answer:
The Montreal Protocol is the treaty known for the ban on production and use of ozone-depleting substances.
