Explanation:

Vestigial structures are defined as structures in an organism that have lost all or most of their original function in the course of evolution. Looking at the options, option B matches this definition. For the picture, option D (assuming it shows a vestigial - like structure, for example, appendix - like structure in a snake or a similar vestigial organ representation) would be the visual representation.
