Answer:
Correct Answer: 11. (d)
Solution:
- Freons or $CFCs$ or chlorofluoro carbons, i.e. $CF _2 Cl _2$ is not the common component of photochemical smog. This smog is produced as the result of tropospheric pollution while freons are the components of stratospheric pollution. These are infact considered as the major cause of ozone layer depletion.
