(a)Toad
(b)Salamander
(c)Newt
(d)Turtle

Answer 1

Hint: It belongs to Phylum Chordata of the Reptilia class. It has four-legged vertebrates in addition to having cold-blooded metabolism and it also has scales that cover their bodies. Breathing is aided by their lungs like altogether other reptiles.

Complete answer:
The reptiles are oviparous, three-chambered heart, and have cold-blooded.
Salamanders belong to amphibia. They are characterized by a lizard-like appearance, and that they have moist skin. They are devoid of scales.
A newt is a semi-aquatic amphibian of the family Salamandridae and can be present in North America, Europe, and Asia.
A toad is any of a number of species of amphibians in the order Anura that are characterized by dry, leathery skin, short legs, and parotid glands.
The turtles belong to the reptiles of the Chelonia. It is described by a unique hard or cartilaginous shell and it is created from their ribs and going about as a shield.

Additional Information: Turtles are divided into two groups, consistent with how they retract their necks into their shells (something the ancestral Proganochelys couldn't do). The system of neck withdrawal varies phylogenetically: the suborder Pleurodira withdraws horizontally aside, foremost to bear supports, while the suborder Cryptodira withdraws straight back, between shoulder supports. These movements are generally because of the morphology and plan of cervical vertebrae. In late turtles, the cervical section comprises nine joints and eight autonomous vertebrae. Since these vertebrae aren't fused and are rounded, the neck is more flexible, bending within the backward and sideways directions.
So the correct answer is ‘Turtle’.

Note: Most turtles that spend most of their lives on land have eyes positioned to look down at objects in front of them. Some aquatic turtles, like snapping and soft-shelled turtles, have eyes closer to the highest of the top. These species can escape from predators in shallow water, where they lie altogether lowered separated from eyes and nostrils. Close to their eyes, ocean turtles have organs that produce pungent tears that freed their assortment of abundant salt ingested from the water they drink.
