Explanation

All four features are common to reptiles like snakes, turtles, and lizards. They have scales covering their bodies (1), breathe using lungs (2), and their eggs have tough, leathery shells (3). As vertebrates, they all possess a notochord during embryonic development (4), which is a defining feature of the phylum Chordata. Therefore, all four characteristics apply.
