For A: While both wings serve the same function (flight), they evolved independently from different ancestral structures. Bird wings evolved from forelimbs of vertebrates, while insect wings evolved from different parts of the body, making them unrelated in origin.
For B: Both eyes serve the same function (vision), but they evolved independently in different evolutionary lineages (humans are vertebrates, squids are mollusks), so they are not derived from a common ancestral structure.
For C: Both species share a common vertebrate ancestor, and their forelimbs evolved from the same basic ...
