Chloroform is an excellent solvent for extracting caffeine from water. The distribution coefficient, KD, (Cchloroform/Cwater) for caffeine in chloroform-water at 25 oC is 10. What relative volumes of chloroform and water should be used for the extraction of 90 per cent of the caffeine from an aqueous solution in a single extraction

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
