Detailed explanation-1: -“Vestigial organs are the organs that have no apparent function and are considered to be the residual parts from the past ancestors.”
Detailed explanation-2: -So, the correct answer is ‘Nails’.
Detailed explanation-3: -A vestigial structure is a biological structure that has lost a major ancestral function and is usually drastically reduced in size. Well-known examples include the eyes of blind cave fishes and blind cave salamanders, and the diminutive wings of kiwis and emus.
Detailed explanation-4: -Vestigial organs are rudimentary anatomical structures that are retained in a species despite having lost their primary ancestral function. These structures often lack an apparent purpose, in contrast to the full functionality of these organs observed in closely related and ancestral species.
Detailed explanation-5: -Thus, the correct answer is ‘Appendix.
