Bird wings and bat wings are examples of which type of organs when their basic bone structure is compared?
Answer and explanation
Correct answer: Homologous organs
When the underlying forelimb bones are compared, bird and bat wings show the same basic skeletal arrangement, even though the wings have adapted for flight in different evolutionary lineages. A shared structural plan is evidence of common ancestry, so they are homologous in this comparison. Option A is correct. Analogous organs would have a similar function but different basic structural origin; vestigial and recessive are not suitable terms here.
