The fish, dog, and bird are alike in many ways. One way is that they all have—
A. legs
B. hair
C. lungs
D. backbones
Answer (3)
D.) backbones Fish don't have legs nor hair nor lungs (they have fins,scales,and gills) Though all of them do have backbones
D. Backbones.
All of the animals listed are vertebrae, a classification of animals that means they have backbones. Fish do not have legs, lungs, or hair, and birds lack hair as well.
The correct answer is D. backbones, as fish, dogs, and birds all share the common characteristic of having a backbone. While fish have fins and gills, dogs have legs and fur, and birds have wings and feathers, none of the other options, such as legs, hair, or lungs, apply to all three animals. Therefore, backbones is the only feature they all possess.
