The accompanying figure shows data on composite values for beak size,beak shape,and body size for the medium ground finch (Geospiza fortis)inhabiting Daphne Major.Complete data sets were collected from 1973 onward.
The figure shows that ________.

A) the population of Geospiza fortis evolved a bigger beak in response to both droughts (1977 and 2003-04)
B) the population of Geospiza fortis evolved a bigger beak in response to the 1977 drought and then evolved a smaller beak in response to the 2003-04 drought
C) the population of Geospiza fortis evolved a smaller beak in response to both droughts (1977 and 2003-04)
D) the population of Geospiza fortis did not evolve at all in response to either drought (1977 and 2003-04)
