With reference to stratospheric ozone depletion, consider the following statements: 1. Chlorine radicals released from Chlorofluorocarbons (CFCs) act as catalysts, meaning they are regenerated and not consumed in the overall ozone destruction process. 2. Polar Stratospheric Clouds (PSCs) provide a catalytic surface that facilitates the conversion of inactive chlorine reservoir species into active chlorine radicals. 3. Ozone depletion is more pronounced over Antarctica because of the extremely low temperatures and the formation of a stable polar vortex. Which of the statements given above is/are correct?

Options:

• A: 1 and 2 only
• B: 1, 2 and 3
• C: 2 and 3 only
• D: 1 and 3 only
