Tiny channels on the footpads of tree frogs give these frogs the abili

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. Irrelevant

(B) At the time when concern was raised over the possible extinction of the tree frog, the actual risk of extinction was greatly overestimated. Incorrect

argument is not concern for possible extinction of the tree frog

(C) The tape was designed by looking at the footpads of the preserved remains of tree frogs that had died of natural causes. Correct

after extinction, tape can be produced from examining preserved remains

(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. Incorrect

not related with conclusion

(E) Tests have shown that the footpads of tree frogs become slightly less adhesive as the frogs age. Irrelevant
