The mammals are the group of warm blooded vertebrate animals that are characterized by the presence of mammary glands. The presence of mammary glands are the chief characteristic of mammals and other important features include presence of neocortex, hair or fur and three middle ears.

Complete answer:
The mammals are the largest order of vertebrates belonging to the class Mammalia. They are warm blooded vertebrates that nourish the young ones from the special types of glands known as the mammary glands. In addition to the mammary glands, the mammals are known to possess certain important and unique characters such as hairs or furs present on the body, arrangement of the lower jaw, three bones in the middle ears, non-nucleated red blood cells.
The representatives of the class Mammalia are found all over the world in various types of environments. They are widely distributed and exhibit great adaptations to their habitats. There are about more than five thousand species of mammals.
India represents a good species of mammals. The mammals in India are represented by various insectivorous, herbivores, even toed ungulates such as pigs, deer, bovina animals such as cow, yak, buffalo, odd toed ungulates such as horses, Chiroptera including bats, lagomorphs such as rabbits, hares, elephants, bears and carnivores such as tiger, lions, panther, leopard etc.
The tiger, which is the member of the genus Panthera, is the national mammal of India. It is a carnivorous animal and is adapted to a variety of habitats such as tropical rain forests, evergreen forests, swamps and mangroves as well as in the savanna and the grasslands. It bears dark vertical stripes on its fur coat. They are the largest species of cat and prey on large ungulates mammals such as deer, antelope etc. It remains solitary and marks its territory. However, due to changes in the environmental conditions such as habitat loss, deforestation, over exploitation have caused a steep decline in the number of surviving animals. Other members of the genus Panthera are lions, panthers, leopards etc.
Bears are members of the family Ursidae and are carnivorous in nature. They have a large bulky body, stocky legs, small rounded ears and plantigrade paws with five non retractile claws and are found in the tropical rain forests, grasslands etc.

Therefore, the correct option is option B.
