A. 4 right and 2 left lobes
B. 2 right and 3 left lobes
C. 2 right and 2 left lobes
D. None of the above

Answer 1

Hint:Rabbits are a member of the class Mammalia of the superclass Tetrapoda. They belong to the phylum Chordata or Vertebrata of the kingdom Animalia. They are subclassified as Eutherian mammals are Placental mammals.

Complete answer:
The zoological name of the rabbit is Oryctolagus cuniculus.
The lungs are the main organs that help in the breathing and the exchange of gases in all mammals. The lungs help rabbits to also perform the process of respiration. Just like all the mammals, the rabbits also have two lungs. The right lung of the rabbit is made up of four different lobes. These four lobes are the anterior azygos lobe, posterior azygos lobe, right anterior lobe, and right posterior lobe. These lobes are also known as the cranial lobe, caudal lobe, middle lobe, and accessory lobe. The left lung of rabbits is made up of two different lobes. These two lobes are the left anterior lobe and left posterior lobe. These lobes are also known as the cranial lobe and the caudal lobe. Moreover, the rabbit has four pulmonary veins. Two of these veins arise from both the lungs.
Thus, based on the above information we can conclude that in rabbits, left and right lungs are divided into 4 right and 2 left lobes.

Hence, the correct answer is an option (A).

Note: Rabbits belong to the order Lagomorpha. The animals of this order possess a different number of teeth in both the jaws. These animals are also known as gnawing animals. This means that both the jaws of these animals are movable. These organisms show pseudo rumination or pseudo coprophagous. This means that they eat their own fecal matter.
