Vermiform appendix is an example of
(A) Analogous organ         (B) Vestigial organ          (C) Homologous organ          (D) All of these

Dear Student,

Option b is correct. 
Vermiform appendix is an example of Vestigial organs.

Vestigial organs are remnants of organs which were complete and functional in the ancestral species but lost their function and became reduced during the course of evolution.

Hope this will help you and clear your doubt.
