Final Answer :
D
Explanation :
Four limbs are a shared derived trait among amphibians, turtles, lizards, snakes, crocodiles, birds, and mammals. All of these animals have four limbs, or are descended from ancestors that had four limbs. This trait is not found in any other group of animals, so it is a useful characteristic for constructing a cladogram that shows their evolutionary relationships.
