Solution
The correct option is B Reptilia
According to the course of animal evolution, class Reptilia is the first class of truly terrestrial animals with creeping movement. They have this creeping movement because their body cannot be lifted up like mammals. These creatures are cold-blooded (poikilotherms) animals. They have dry and scaly skin and do not have external ears.
