请教一道 lsat（14）题

At the more trivial end, orthodox medicine is largely ineffective in treating aches, pains and allergies, and, at the other extreme, it has yet to produce a cure for serious, life-threatening diseases such as advanced cancer and lupus. People turn to alternative medicine when orthodox medicine fails to help them and when it produces side effects that are unacceptable to them.

(D) There are no effective medical treatments that are free from unacceptable side effects
(E) Orthodox medicine will eventually produce a solution for the diseases that are currently incurable
19. The charge made above against alternative medicine is most seriously weakened if it is true that
(A) predictions based on orthodox medicine have sometimes failed, as when a patient has recovered despite the judgment of doctors that an illness is fatal
(B) alternative medicine relies on concepts of the body and of the nature of healing that differ from those on which orthodox medicine is based
