Question

Herpetology is study of
A. Reptiles and amphibians
B. Snakes
C. Helminths
D. Mammals

Answer 1

Hint:- Herpetology is a branch of zoology that includes the study of biology, ecology, behaviour, taxonomy and husbandry of certain organisms.

Complete step-by-step solution:-
Herpetology is evolving as a discipline, a branch of zoology coping with the study of amphibians and reptiles helping the researchers in providing a major insight of terrestrial and aquatic ecosystems.
Like most other fields of vertebrate biology (e.g., ichthyology, mammalogy), herpetology consists of a variety of cross-disciplines: behaviour, ecology, physiology, anatomy, paleontology, taxonomy, and others. The field of herpetology can further be subdivided into areas dealing with particular taxonomic groups such as frogs (batrachology), snakes (ophiology or ophidiology), lizards (saurology) or turtles. A herpetologist uses amphibians or reptiles as model organisms for specific questions in the field of study.
Herpetology as a unified science apparently stems from the traditional tendency to lump together all creeping animals. Modern herpetology may be a popular science, within which amateurs have made many valuable contributions in such areas as distribution, behaviour, and even taxonomy. The foremost a part of the more technical research is meted out at universities and museums, further as within the field.
Research into the biology of various amphibians and reptiles has contributed much to the sphere of general biology as for instance, larval frogs and salamanders within the understanding of embryological concepts, iguanid lizards with the event of the sub-discipline of population ecology, and venom in increasing the understanding of human cardiac and neurological disorders.
Therefore, the correct option is reptiles and amphibians.

Note:-
- Ophiology is the study of snakes
- Helminthology is the study of helminths
- Mammalogy is the study of mammals
- However, a paleontologist is more likely to figure with both amphibians and reptiles or with intermediate forms.
