An island is colonized by a single species of finch-like birds with beak shapes adapted for different feeding methods. The major type of food on the island is the trumpet creeper flower. The flower and bird beaks are shown in the images. According to natural selection, which will most likely happen to the species of bird after several generations living on the island?

A Individuals with beak A will change their beak shape to access food in the flower.

B Individuals with beak B will be more successful finding food and will reproduce, becoming the main variety of bird.

C Individuals with beak C will cause plants with larger seeds to grow on the island, reducing the number of birds with beak B.

D Individuals with beak D will produce the same number of offspring as the other birds.
