A student studying the efficacy of a new herbal medicine found that of a group of 500 people who regularly took 500 mg of the medicine daily for a year, fewer than 10 percent suffered serious bouts of flu. Of a group of 500 people who took 100 mg (the recommended dosage) of the medicine daily for a year, 40 percent suffered at least one serious bout of flu, and of a group of 500 people who did not take the medicine, 35 percent suffered at least one serious bout of flu.
Which of the following hypotheses is best supported by the evidence above?
(A) The herbal extract has no medicinal value, it is merely a placebo.
(B) Massive doses of the herbal extract can help to prevent a serious bout of flu.
(C) Doses of the herbal extract that exceeds the recommended daily dosage by 500 percent will reduce the incidence of serious bouts of flu by 25%.
(D) The herbal extract is helpful in preventing flu.
(E) The effectiveness of the herbal extract in preventing serious bouts of flu increases in direct proportion to the amount of extract taken.

I saw this in a prep book stating the answer as B. IMO it is A. Can someone explain the reasoning behind this?

As for option B, what is the range of massive? How much of massive is safe and what level of massive can kill? Also, for option E, increment in proportion... to what point? But one thing is certain, it's not a placebo, it actually helps, only that it does at a particular level of dosage. My opinion...
