Correct option: D
C∙l+CF2∙Cl\mathop \mathrm{C}\limits^ \bullet \mathrm{l + C}\mathop {{\mathrm{F}_2}}\limits^ \bullet \mathrm{Cl}
Option D (C∙l+CF2∙Cl\mathop \mathrm{C}\limits^ \bullet \mathrm{l + C}\mathop {{{{F}}_2}}\limits^ \bullet \mathrm{Cl}) is correct because the gas 'A' is a CFC (Chlorofluorocarbon), which upon UV radiation dissociates into chlorine free radical and a fluorocarbon free radical.
