Correct Option (c) Reason : Vestigial organs are non-functional, degenerate and rudimentary organs that correspond to fully developed and functional organs of related organisms, e.g. nictitating membranes, muscles of ear pinna and third molar (wisdom tooth), mammary gland in males, coccyx (caudal vertebrae), vermiform appendix etc.
