उत्तर
Eyelids
Explanation:
Among the options given, eyelids are not vestigial organs in humans. Vestigial organs are remnants of organs that were functional in ancestors but are reduced or non-functional in humans. The muscles of the ear pinna, nictitating membrane, and vermiform appendix are considered vestigial because they serve little or no useful purpose in humans, while eyelids are fully functional and essential for eye protection and moisture retention.
