Human ear muscles and appendix can be placed under which type of organs?
Answer and explanation
Correct answer: Vestigial organs
The governing concept is vestigial structures. Some human ear muscles have little voluntary use for most people, and the appendix is a reduced structure compared with the more functional caecum of some ancestors or related animals. Such structures may retain limited functions, but their reduced role reflects evolutionary history. They are not analogous organs, chromosomes, or traits; therefore option A is the best answer.
