Which of the following gases causes depletion in ozone layer?

Step-by-step solution

The ozone layer in the stratosphere protects Earth from harmful ultraviolet radiation. Depletion occurs primarily through catalytic reactions with certain chemical species. Helium is inert and non-reactive with ozone. Carbon dioxide contributes to global warming but does not deplete ozone. Hydrogen gas shows no known ozone-depleting properties. Nitric oxide participates in a catalytic cycle: NO + O₃ NO₂ + O₂ NO₂ + O NO + O₂ The net reaction is O₃ + O 2O₂ , with nitric oxide acting as a catalyst to destroy ozone mol
