Which statement provides the best argument for why bird and butterfly wings evolved to have a similar function but differ in structure?

a
This is an example of vestigial structures, which indicates that the common ancestor of birds and butterflies had the same structure as birds.
b
This is an example of homologous structures, which indicates that they share a common evolutionary origin.
c
This is an example of embryological structures, which indicates that bird and butterfly wings have similar function because they develop in much the same way.
d
This is an example of analogous structures, which indicates that they are not closely related even though they perform the same function.

b
This is an example of homologous structures, which indicates that they share a common evolutionary origin.

This is the best argument because homologous structures suggest that bird and butterfly wings evolved from a common ancestor and have similar functions but differing structures due to adaptations to different environments or ecological niches.
