Tiny channels on the footpads of tree frogs give these frogs the ability to repeatedly adhere to surfaces without the cracking that occurs when adhesive tape is reused in a similar manner. A new commercially available tape mimics these channels, not only giving the tape the ability to be reused many times, but also increasing the tape’s adhesiveness. If tree frogs had become extinct five years ago, as was feared at the time, this tape would not now be available.
Which of the following most weakens the conclusion in the argument above?
(A) The footpads of tree frogs are not as adhesive as the foot pads of certain lizards that are in no danger of extinction.
(B) At the time when concern was raised over the possible extinction of the tree frog, the actual risk of extinction was greatly overestimated.
(C) The tape was designed by looking at the footpads of the preserved remains of tree frogs that had died of natural causes.
(D) A commercially available adhesive tape that has been chemically treated can be reused in much the same manner as the tape that mimics the footpads of tree frogs.
(E) Tests have shown that the footpads of tree frogs become slightly less adhesive as the frogs age.

The bolded part is the conclusion of the argument above.
We need to bring something to the table, that weakens the extinction clause mentioned.
If we are able to say, the same foot pads were found in other organisms apart from, tree frogs.or
even after extinct if we are able to analyse the foot pads. Then that options weaken the conclusion.
(A) The footpads of tree frogs are not as adhesive as the foot pads of certain lizards that are in no danger of extinction.comapres foot frogs with lizards, but says adhesive not as same. So can’t weaken. Even though a different organism comparison is proposed.
(B) At the time when concern was raised over the possible extinction of the tree frog, the actual risk of extinction was greatly overestimated.No evidence to support the risk of extinction being overestimated. Out of scope.
(C) The tape was designed by looking at the footpads of the preserved remains of tree frogs that had died of natural causes.
Having died of natural causes, put forth the idea that the tiny channels within foot pad are intact. From their remains we can ascertain the adhesive nature.
(D) A commercially available adhesive tape that has been chemically treated can be reused in much the same manner as the tape that mimics the footpads of tree frogs.This statement provides a different product which is similar to the foot pads of tree frogs. But, the conclusion statement about extinction of tree frogs is no where correlated. So even though it might feel as a weakener, it doesn’t weaken the conclusion.
(E) Tests have shown that the footpads of tree frogs become slightly less adhesive as the frogs age.
Out of scope. Age is not related .
hence,
option C
