The explanation that accounts for the characteristics of Darwin's finches, including their similarities and differences in beak size and shape, is:
**C. all finch species evolved from a common ancestor.**
This reflects the concept of adaptive radiation, where a single ancestral species evolves into multiple species, each adapted to different ecological niches and food resources, leading to variations in traits such as beak size and shape.
