Hint Their scales protect them from everyday wear and tear and from injury. These are mostly made of a hard substance called keratin. This is very tough and waterproof, it stops the reptiles from drying out.

Complete answer:
Reptiles have dry, scaly skin. The skin of reptiles is roofed with scutes or scales which, alongside various other characteristics, discriminate reptiles from animals of other classes. Reptile scales are frequently brightly colored and differ in shape and size throughout their body. Scales are made from alpha and beta-keratin and are developed from the epidermis (contrary to fish, during which the scales are developed from the dermis). They could be ossified or tubercular, as within the case of lizards, or altered complex, as within the case of snakes. Reptiles shed their skin by a procedure known as ecdysis which takes place continuously throughout their lifetime.

Additional information:
Reptilian skin is roofed during a horny epidermis, creating it watertight and making reptiles to measure on land, in contrast to amphibians. Compared to mammalian skin, that of reptiles is quite thin and does not possess the thick dermal layer that builds leather in mammals. Exposed parts of reptiles are protected through scales or scutes, occasionally with a bony bottom (osteoderms), making armor. In Lepidosauria, like lizards and snakes, the entire skin is roofed in overlapping epidermal scales. Such scales were once known to be classical of the category Reptilia as an entire, but are now known to occur only in Lepidosauria. The scales present in turtles and crocodiles are of dermal, instead of epidermal, origin and are properly known as scutes.

So, the correct answer is 'Dry scales'.

Note: In turtles, the body is hidden inside a hard shell composed of fused scutes. Lacking a thick dermis, reptilian leather isn't as strong as mammalian leather. It is utilized in leather-wares for decorative purposes for shoes, belts , and purses, particularly crocodile skin. Snakes, on other hand, renew their skin by crawling out of their old skin, often discarding it in one piece.
