Solution

The correct option is C Chlorine radical
These three types of steps are encountered in every free-radical reaction.
The bottom line here is that by counting the number of radicals created or destroyed in each step, you can determine if the step is initiation, propagation, or termination.
Intiation -> net formation of radicals
Propagation -> no change in the number of free radicals
Termination -> net destruction of free radicals
Option D is correct.
