Vedclass · Answer

(B) vestigial organ is an anatomical structure that has lost most or all of its original function through the process of evolution. In humans,the nictitating membrane (also known as the plica semilunaris) is a vestigial remnant of the third eyelid found in many other vertebrates. While ear pinna muscles exist,they are not considered the primary vestigial organ in this context compared to the nictitating membrane. Mammary glands in males are present but are not typically classified as vestigial organs in the same sense as the nictitating membrane or appendix. Therefore,the correct option is $B$.
