A drug that is highly effective in treating many types of infection can, at present, be obtained only from the bark of the ibora, a tree that is quite rare in the wild. It takes the bark of 5,000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibora’s extinction.

Which of the following, if true, most seriously weakens the argument above?

(A) The drug made from ibora bark is dispensed to doctors from a central authority.
(B) The drug made from ibora bark is expensive to produce.
(C) The leaves of the ibora are used in a number of medical products.
(D) The ibora can be propagated from cuttings and grown under cultivation.
(E) The ibora generally grows in largely inaccessible places.


Conclusion: that continued production of the drug must inevitably lead to the ibora’s extinction.
Assumptions:
That drug is made only from Ibora tree
Number of trees grown proportion is less compared trees being cut for making the drug

Let me try analyzing the options:
(A) The drug made from ibora bark is dispensed to doctors from a central authority. - Irrelevant - Dispensed to doctor from central authority has nothing to do with the extenction of the tree
(B) The drug made from ibora bark is expensive to produce. - Out of scope - Expensive to produce - But this have nothing to with distinction. Even if its extensive the drun will be made and info expensive is out of scope
(C) The leaves of the ibora are used in a number of medical products. - May be strengthener - becuase the leaves are used in number of medical products which help in extenction of this Ibora tree
(D) The ibora can be propagated from cuttings and grown under cultivation. - Good weakener - Because if these trees are grown in cultiavation then this can give an alternate view for the Ibora extinction i.e. Conclusion
(E) The ibora generally grows in largely inaccessible places - Irreveleant
