Because people are living longer, they are developing more new types

Each of the following, if true, weakens the conclusion above EXCEPT:

(A) If forced to reduce their prices for the new drugs, pharmaceutical companies could not afford to develop drugs for the prevention of more new ailments. (Opposite answer, this clearly weakens the conclusion.)

(B) The new drugs prevent not only new types of ailments but also ailments already common among elderly people. (This is not a straight answer like option A, you need to infer this as if these drugs have so many benefits, the prices will not be low.)

(C) Other new drugs are available to treat, but not prevent, the same new ailments. (This is also not a straight answer, I kind of inferred that as the other new drugs are not as effective as the ones that are beneficial therefore the government won't be successful in making the pharmaceutical companies lower prices.)

(D) None of the new drugs has been shown to prolong an elderly person’s life. (This is our answer, as it clearly states that there is no point taking the new prescription drugs as other than temporarily curing people from the new ailments it is not going to add to the lifespan of the people, so the price of those drugs doesn't matter.)

(E) The federal health insurance program for the elderly covers all medical expenses of the elderly other than prescription drugs. (Already stated in the stimulus. would have been the right answer had option D not been present which is a better option in my opinion that E)
