Suppose that botanists have discovered a new plant hormone and they hypothesize that it is required for normal leaf shape.Which experimental result would not support this hypothesis?
A) A mutant with abnormal leaf shape is found to lack the hypothesized hormone.
B) A chemical that is isolated is found to affect leaf shape when applied to the young tip of developing plants.
C) Plants in which the synthesis of the hypothesized hormone is inhibited develop abnormal leaves.
D) Removal of the young tip of the plant causes the development of abnormal leaf shape.
E) Treatment of a leaf-shape mutant plant with the hypothesized hormone restores normal leaf development.

Removal of the young tip of the plant causing abnormal leaf shape does not directly relate to the presence or absence of the hormone, as it could be due to other factors such as the removal of a growth center.
