- A. Aug - Nov
- B. Sep - Nov
- C. Nov - Dec
- D. Dec - Jan
Explanation
The Antarctic ozone hole reaches its greatest seasonal depletion during the Southern Hemisphere spring, especially from September to November. Students may choose August to November because depletion begins in August, but the standard period of substantial depletion is September to November.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
