• A. January 1, 1990
• B. September 16, 1987
• C. July 4, 1986
• D. March 15, 1988

Answer: (B)

The Montreal Protocol was signed on September 16, 1987, as an international treaty designed to protect the ozone layer by phasing out the production and consumption of numerous substances responsible for ozone depletion, particularly chlorofluorocarbons (CFCs). This date is significant because it marked the beginning of global efforts to address environmental concerns related to ozone layer damage, which plays a critical role in protecting life on Earth from harmful ultraviolet radiation. The protocol was a result of increasing scientific evidence linking human-made chemicals to the depletion of the ozone layer, and it has since undergone several amendments to enhance its effectiveness. The success of the Montreal Protocol has been celebrated as a major environmental achievement, demonstrating how countries can come together to address global challenges. The other dates listed do not correspond to the signing of the Montreal Protocol, making the correct choice essential for an accurate understanding of this pivotal environmental treaty.
