D
None of the above
Explanation: 

Detailed explanation-1: -Beneath their scales reptiles have a watertight skin that allows them to exist on dry land, unlike their amphibian counterparts.

Detailed explanation-2: -The keratin that makes up their skin is the same material as mammalian hair and finger nails. This impermeable skin allows reptiles like sea snakes and crocodiles to live in saline [salty] environments. Their skin can be considered mostly waterproof and they do not dry out easily.

Detailed explanation-3: -Reptiles have a tough, dry, scaly skin that protects them from predators and allows them to live in dry places by reducing water loss. Reptilian scales are made of keratin, like hair, and found in an overlapping arrangement. This creates a sort of environmental shield for the animal.

Detailed explanation-4: -Reptile skin is a solid sheet of keratin scales. Keratin is the same substance as human hair and nails. This makes it waterproof and prevents the reptile’s internal fluids from evaporating.
