c. Chordata, Amphibia, Gnathostomata, Craniata, Tigrina
d. Chordata, Craniata, Amphibia, Gnathostomata, Tigrina
e. Gnathostomata, Craniata, Chordata, Rana, Tigrina

Answer 1

Hint: Rana tigrina is the scientific name of the frog. It is a solitary and nocturnal animal and it is found mainly in bushes near water bodies. Their body colour ranges from yellow to olive green and they have dark patches all over their body.

Complete answer:
The members of kingdom Animalia are further classified into Phylum, Class, Order, Family, and Genus based on certain identifiable characteristic features.
(i) Chordata - The species having a spinal cord. Chordates are animals characterized by the presence of notochord at some stage during their development.
(ii) Craniata - The species that have a cranium or skull.
(iii) Amphibia - The species which live on both land and water. They are cold-blooded animals and require an aquatic habitat to lay eggs. These organisms are mainly characterized by two pairs of limbs, smooth and moist skin for respiration. They also possess protruding eyes which are protected by usually more than one pair of eyelids.
(iv) Gnathostomata - Jawed vertebrates
(v) Rana - Genus
(vi) tigrina - Species
Rana tigrina is the scientific name of the bullfrog found in India. Generally, the classification is done by seeing the common morphology(structure) of the frog. The frog has a spinal cord so it belongs to Phylum Chordata. The skeletal structure reveals the presence of a skull so Craniata. The frogs also possess distinct jaws so they can be placed in the superclass Gnathostomata. Frogs live in both land and water-class Amphibia. Rana is the genus and tigrina is the species.

Hence the correct answer is B) Chordata, Craniata, Gnathostomata, Amphibia, Rana.

Note: The naming of an organism is done as per the rules under binomial nomenclature. The rules are,
- There are two names, the generic and specific epithet.
- The first letter of genus is always capital and the first letter of species is small.
- The genus and species are of latin origin and thus must be italicized when typed.
- When written using pen and paper, they must be written separately and underlined.
