Rana tigrina is the scientific name of the bullfrog found in India. We will start 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 have also distinct jaws so they can be placed in the superclass Gnathostomata. Frogs live in both land and water-class Amphibia. and Rana is the genus.
So, the correct answer is 'Chordata, Craniata, Gnathostomata, Amphibia, Rana'.
