Human arm and bird wing are examples of which type of organs?
Answer and explanation
Correct answer: Homologous organs
The governing concept is homology, in which organs retain a similar underlying structural plan because of common ancestry, even when their functions differ. The human arm is adapted mainly for manipulation, while a bird wing is adapted for flight, but both contain corresponding bones such as the upper arm, forearm and hand elements. Therefore option A is correct. They are not analogous, acquired or fossil organs.
