The correct reason why these limbs provide evidence of common ancestry is:
**They have a similar structure.**
This similarity in structure, known as homologous structures, suggests that different species have evolved from a common ancestor. Even though the limbs may serve different functions in different organisms, their underlying anatomical similarities indicate a shared evolutionary origin. The other options, such as being the same size or performing the same function, do not necessarily indicate common ancestry.
