B Correct answer
Explanation

Analogous structures serve similar functions but have different evolutionary origins and structural designs. Examples include the wings of bats (mammals) and insects (arthropods), or the flippers of penguins (birds) and dolphins (mammals). They result from convergent evolution where unrelated species adapt to similar environmental challenges.
