Solution

The correct option is A Columella auris
Columella auris in amphibians (frogs) and even in reptiles and birds is a bony or cartilaginous rod connecting the tympanic membrane with the inner ear and transmitting sound. It is homologous to the hyomandibular bone in fish and embryologically to stapes in mammals.
So, the correct answer is option D.
