the basic idea of choice C is "there are other industries that have the same problem the pharma guys have—and for them the problem is even worse."
...this clearly doesn't help. if anything, it goes the opposite way (by making the pharma industry's situation seem LESS 'special').
i'm not seeing any benefit from using specific numbers here.
the only numerical relationship in this problem is 'THIS ratio is higher than THAT one', which is easy to understand without specific values.
(can you understand 'I'm shorter than my brother' without plugging in specific heights? i bet you can. this situation is no more complicated.)
