Step 1: Comprehension Check:
The query requires identification of the international environmental accord specifically designed to safeguard the ozone layer by ceasing the production and use of chemicals that degrade it.
Step 3: In-depth Analysis:
\[\begin{array}{rl} \bullet & \text{(B) Montreal Protocol: The Montreal Protocol on Substances that Deplete the Ozone Layer (1987) stands as a pivotal international agreement aimed at protecting the ozone layer by progressively eliminating the manufacturing and consumption of numerous ozone-depleting substances, such as chlorofluorocarbons (CFCs) and halons. It is widely recognized as one of the most effective environmental treaties established.} \\ \bullet & \text{(A) Kyoto Protocol: This international accord obliged signatory states to reduce greenhouse gas emissions, based on the scientific consensus regarding global warming and the role of human-generated CO\(_2\) emissions. Its focus was climate change, not ozone depletion.} \\ \bullet & \text{(C) Paris Agreement: Adopted in 2015, this is a legally binding international treaty on climate change. Its objective is to restrict global warming to well below 2 degrees Celsius, ideally to 1.5 degrees Celsius, relative to pre-industrial levels. Its focus is climate change.} \\ \bullet & \text{(D) Geneva Protocol: This treaty prohibits the use of chemical and biological weapons in international armed conflicts. It holds no relevance to environmental matters.} \\ \end{array}\]
Step 4: Conclusion:
The Montreal Protocol is the treaty renowned for its prohibition on the production and use of ozone-depleting substances.
