Question

Herpetology is a branch of science which deals with
(a)Aves
(b)Mammals
(c)Reptiles
(d)Fishes

Answer 1

Hint: The meaning of hepatology means creeping or crawling so it includes the organisms that crawl on the surface in order to move and also the ones that live on both land and water some examples are snakes, frogs, etc.

Complete answer:
As the name suggests, herpetology is known as the study of crawling and creeping animals belonging to the class reptilia and class amphibia of phylum Chordata. So all the animals that come under the classes amphibia and reptilia are then studied in this particular branch of science.

Additional Information:
Some characteristic features of Reptiles are:
The reptiles are a monophyletic group that comes under the group Vertebrata and they represent the second major living lineage of amniotes besides mammals. Their skin is made water-resistant by a layer of scales made up of keratin. Reptiles breathe air through well-developed lungs. Reptiles lay shelled, amniotic eggs, or in some cases retain embryos internally and give birth to live young. Some reptilian members are lizards, snakes, turtles, crocodiles, and alligators.
Some characteristic features of amphibians:
The first tetrapods to live on land were amphibians, meaning “both-sides-living.”
The name is appropriate because adults of most amphibians feed on land but lay their eggs in water. Most amphibians undergo metamorphosis from an aquatic larva to terrestrial or semi-terrestrial adults. Living amphibians represent a monophyletic group, Amphibia, which includes frogs and toads, salamanders, and the snakelike caecilians.
So, the correct answer is ‘reptiles’

Note: -The fossil record for reptiles includes the dinosaurs, ichthyosaurs, plesiosaurs, pterosaurs that flourished from about 250 million years ago.
-The fossil record shows clearly that internal fertilization and live birth (viviparity) evolved during the radiation of Devonian fishes. However, the ancestral tetrapod is hypothesized to have been egg-laying (oviparous).
