Concept:

This question is based on ozone depletion pollutants.

Solution:

The major pollutants responsible for ozone depletion are chlorofluorocarbons (CFCs) and nitrogen oxides (NOx).

From the given list, these are $NO_{2}$ and $CFC . N_{2}$ and $O_{2}$ are not pollutants.

The pollutants from the list are $SO_{2}, CO_{2}, CO, NO_{2}, CH_{4}, CFC, Cl_{2}, Br_{2}, I_{2}, N_{2}, He$ , Ne. The chief pollutants for ozone depletion are $NO_{2}$ and CFC s.

Total number of chief pollutants from the list is 2 .

Final Answer: The number of chief pollutants is 2 .
