Which of the following, if true, most seriously undermines the advertisementâ€™s argument?
(A) Some competing brands of painkillers are intended to reduce other kinds of pain in addition to sinus pain.
(B) Many hospitals that do not usually use Novex will do so for those patients who cannot tolerate the drug the hospitals usually use.
(C) Many drug manufacturers increase sales of their products to hospitals by selling these products to the hospitals at the lowest price the manufacturers can afford.
(D) Unlike some competing brands of painkillers, Novex is available from pharmacies without a doctorâ€™s prescription.
(E) In clinical trials Novex has been found more effective than competing brands of painkillers that have been on the market longer than Novex.
I remember encountering this problem when I did OG11th edition and when I saw it on CR1000, I knew what the answer was. But on OG11

in CR1000 (Test 15 problem 6) the answer is D
I assume that OG11
