问weaken.
字面角度分析
c. Many drug manufacturers increase sales at their products to hospitals by selling these products to the hospitals at the lowest prices the manufacturers can afford.
原文没有提到价格问题,而且要压价可以都压价Novex不一定就有比较优势.
d. Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctor's prescriptions.
Unlike some competing brands of painkillers....不光说明了Novex是非处方药还说明了其它的牌子是处方药. 谁头痛想买就可以买N而不用预约医生看病以后才可以买.
所以这个一个明显的引入它因的削结论的方式.

从Reasioning line 角度分析
广告: 因为3/4hospitals give their patient Novex---------->Novex is the most effective painkiller------->

C: 因为 Convenience----->3/4 hospitals give their patient Novex ------>Novex is the most convenience painkiller (就推不出来广告中的结论了)
提出它因来削弱.
