Solution : The correct answer is (A) Both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
Statement 1 is accurate in stating that the Montreal Protocol is an international environmental agreement aimed at protecting the ozone layer.

Statement 2 provides the correct explanation for statement 1. The Montreal Protocol indeed restricts the production and consumption of ozone-depleting substances. It sets specific control measures and timetables for the phased reduction and elimination of ODS, including substances like chlorofluorocarbons (CFCs) commonly used in refrigeration, air conditioning, and aerosol propellants.
Therefore, both statement 1 and statement 2 are true, and statement 2 is the correct explanation of statement 1 .
