Options
A Unrelated ancestry
B Common evolutionary origin
Correct Answer
C Functional differences
D Environmental isolation
Correct Answer

Option B is the correct answer.

Detailed Explanation

Homologous structures are anatomical features in different species that are similar because they were inherited from a common ancestor, even if they now serve different functions (e.g., the forelimbs of humans, cats, whales, and bats).

Hint

Similar structure, different function, indicates shared ancestry.
