By examining the fossilized leaves of any prehistoric plant it is possible to determine the climate in which that specimen grew because the size and shape of a leaf are unique to a given climate. Since the climate at a given location depends on the altitude at that location, it follows that the size and shape of a fossilized leaf also indicates the altitude at which the plant grew. The reasoning in the argument is vulnerable to criticism on the grounds that it
A: treats the size and shape of a leaf as if they were the only physical characteristics of a leaf that depend on climate
B: relies on a weak analogy between a leaf and the fossil of a leaf as evidence for the claims advanced
C: fails to demonstrate that no species of plant can long survive a violent change in its environment
D: overlooks the possibility that locations at different altitudes can have the same climate
Choose A, B, C or D as your solution.
