Vedclass · Answer

(B) The group of animals possessing a cranium,vertebral column,ventral heart,and pulmonary respiration is classified under the subphylum $Vertebrata$.Within $Vertebrata$,the superclass $Tetrapoda$ is specifically defined by the presence of two pairs of limbs (pentadactyl limbs).While $Vertebrata$ includes all animals with a cranium and vertebral column,$Tetrapoda$ is a more specific (smaller) taxonomic group that includes amphibians,reptiles,birds,and mammals,all of which possess two pairs of limbs.Therefore,$Tetrapoda$ is the smallest taxonomic group among the options that satisfies all the given criteria.

Which of the following is the smallest taxonomic group of animals having a cranium,vertebral column,ventral heart,pulmonary respiration,and two pairs of limbs?
