Answer 1

Hint: Definite categories or ranks in the classification of plants, animals, and other organisms are kingdom, phylum, class, order, family, genus, species. Animals that have milk-producing glands come under Mammalia class and Mammalia comes under Chordata phylum.

Complete answer: Classification of living organisms is not a simple process but it involves many steps like it involves a hierarchy of steps in which each step shows a rank or category. The category is a part of the taxonomic arrangement, it is called the "taxonomic category" and all categories together form the taxonomic hierarchy. The seven obligate categories in which all living organisms are classified are arranged in a descending sequence starting from kingdom to species or in ascending order from species to kingdom. The term phylum is used for animals, while diversity is commonly used for plants. It is a category higher than that of class. Phylum or division is a group of related classes. Animals like fishes, amphibians, reptiles, birds, and mammals. All of these different organisms and placed in the phylum Chordata as all of the animals in these classes have some common characteristics like the presence of notochord at least at some stage of their lives, dorsal hollow neural system. So the tiger's phylum is Chordata.
-Class: A class is a group of one or more related orders. The tiger belongs to the Mammalia class. In a Mammalia group, some features are milk producing glands and hair on the skin.
-Order: It is a group of related families that mean related families are kept in the same order. Tiger belongs to the Carnivora order. Some features of Carnivora are the presence of canine teeth.
-Family: It includes various groups of related genera, which share less number of similarities as compared to that at the genus and species level. Tiger comes under the Felidae family.
-Genus: Genus is a group of related species, which has more characters in common in comparison to species of other genera. Tiger comes under the Panthera genus.
-Species: It is a natural population of individuals or groups of populations which resemble one another in all essential morphological and reproductive ways so that they can easily interbreed freely in nature to produce fertile offsprings. On the basis of taxonomic studies, a group of individuals/populations with fundamental similarities are referred to as species. Tiger belongs to tigris species.
So, the correct answer is (B).

Note: Kingdom is the highest category in the taxonomic hierarchy. It is a group of phyla or divisions, which have certain basic common characteristics. Animals present in all phyla lack cell walls and chlorophyll, placed in the kingdom Animalia.
