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 5000 trees to make one kilogram of the drug. It follows, therefore, that continued production of the drug must inevitably lead to the ibore's extinction. Which of the following,if true, most seriously weakens the arguments above ?
A The drug made from the ibora bark is dispensed to doctors from a central authority
B The drug made from the 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
