A. Python

B. Sphenodon

C. Turtle/Tortoise

D. Frog   

Answer 1

Hint: Reptiles are considered to be evolved from animals like dinosaurs. Dinosaurs dominated the Mesozoic era hence it can also be called the age of reptiles. The dominance of dinosaurs came to an end of the Cretaceous era. Reptiles like- snakes, lizards. Lizards started losing their legs and they evolved into snakes. It is one of the largest histories of the world- the Mesozoic era. 

Complete answer:

Reptile is an an animal that crawls or moves on its belly (such as a snake) or on small short legs (such as a lizard), class Reptilia includes of cold-blooded, air-breathing, usually egg-laying vertebrates that include the alligators and crocodiles, lizards, snakes, turtles, and extinct related forms (such as dinosaurs and pterosaurs) and that have a body typically covered with scales or bony plates and a bony skeleton with a single occipital condyle, a distinct quadrate bone usually immovably articulated with the skull, and ribs attached to the sternum.

Option A python- python is the kind of crawling animal or reptile which has no limbs but only a tail. It glides in a sideways or front way pattern with its tail. Pythons are usually terrestrial animals while some species of python are seen to be aquatic. They do not lie in both water and land. 

Option A is not correct.

Option B Sphenodon- Sphenodon is a lizard-like reptilian (living fossil) found in New Zealand. It is placed in an order called Rhynchocephalian. They belong to the animal kingdom animalia of-course. They are land animals. 

Option B is not correct.

Option C Turtle/Tortoise- turtle or tortoise belongs to the class reptilia and are said to be both living on land as well as water but not for several hours. They are basically termed as aquatic animals. They move to land to lay eggs and then return back to water. As in water there are several predators and no space to lay eggs. So, they find land much safer to lay eggs.

Option C is correct.

Option D Frog- frogs are known to be staying in both land and water. It is an exceptional animal which can survive and thrive both in land as well as water. Hence it is called an amphibian and it does not belong to the class reptilia. Animals which live in both land and water are called amphibians. 

Option D is not correct.

Hence, Option (C) is the correct answer.

Note:

Reptiles have been seen growling. They have been heard to emit growls when disturbed and a range of other vocalizations have been reported in captive specimens. They are very silent creatures in general but their attack is powerful and it helps them to catch prey easily. Most reptiles have a carnivorous diet. They feed on small insects. Usually, they have a creeping and crawling mode of locomotion. Examples can be lizards, crocodiles, alligators etc.
