Answer:

D. Jaws and paired appendages

Explanation:

Two pairs of appendages are present in sharks, birds and  salamanders. In the shark (fish) these appendages are fins, while in birds and  salamanders (land vertebrates) the appendages are limbs.  

Sharks, birds and  salamanders also have jaws. The jaw is an opposable articulated structure, typically used for grasping and manipulating food. Most vertebrates have jaws.
