d, are exactly the same and used for the same function no matter what species they are found in

Answer 1

Answer: b, come from a common ancestor.

Step-by-step explanation:

Homologous structures are body structures found in different species with similar structures, indicating a shared evolutionary history. These structures may have different functions in different species but share a similar underlying structure. Examples of homologous structures include the bones in the forelimbs of vertebrates, which have alike arrangements and structures despite being used for different purposes (e.g., wings in birds, arms in humans, and flippers in whales).
