Show answer & explanation
Correct answer: D
The correct sequence for ozone hole formation begins with pre-conditioning (C), followed by de-humidification and de-nitrification (A). This leads to vortex formation (B) where very low temperatures allow polar stratospheric clouds (D) to form. Finally, catalytic ozone destruction occurs (E).
