(b)Fish
(c)Frog
(d)Horse

Answer 1

Hint: The animals that live on both land and in water are known as amphibians meaning two-lives. There are about 8,000 different species of amphibians. One of these animals has a larval stage called tadpole that lives in water and moves to land as it grows into an adult.

Complete answer:
Amphibians are ectothermic, tetrapod animals. Most amphibians start out as larvae that live in water only and then later they develop structures that allow them to live on land too. In the case of a frog, this larva is called a tadpole.
Frogs are an example of Amphibians.

Additional Information:
In all amphibians, the young organisms undergo metamorphosis from a larva with gills to an adult with lungs as the organ of breathing. Amphibians also use their skin as a secondary respiratory surface and certain small salamanders and frogs even completely lack the lungs and use skin for respiration on land.
Some aquatic salamanders retain their gills as aquatic adults and are classified as amphibians on the basis of other common features.
So, the correct answer is, “Frog”

Note:
-The order Anura which contains both frogs and toads, is the largest order of the amphibians.
-Many times frogs and toads are confused with each other though there are many differences among these two families of organisms.
-Frogs have moist and smooth skin. They have teeth in their upper jaw however they lack parotid glands.
-Toads have dry and rough skin with rigid bodies. They do not have any teeth. They have parotid glands on their heads that produce poisonous secretions.
