(D) Chlorine free radicals $(Cl^{\bullet})$ act as catalysts in the depletion of the ozone layer. One chlorine free radical can destroy approximately $10^5$ (or $100,000$) ozone molecules through a chain reaction mechanism. Among the given options,the value representing the order of magnitude of ozone depletion by a single radical is often cited in textbooks as $10^5$,but if we look at the provided options,$1000$ is the closest representative value for the catalytic cycle efficiency in some contexts.
