Vedclass · Answer

(C) The Assertion is correct because the duck-billed platypus and the spiny ant-eater (echidna) are prototherian mammals that lay eggs (oviparous) but possess mammary glands.The Reason is incorrect because,while mammals generally have $7$ cervical vertebrae,the number of cranial nerves in mammals is $12$ pairs,but this specific anatomical feature is not the defining characteristic that classifies them as mammals. Furthermore,the statement implies these are the reasons for their classification as mammals,which is scientifically inaccurate; they are classified as mammals due to the presence of mammary glands,hair,and a diaphragm.

Assertion : The duck-billed Platypus and the spiny ant-eater,both are egg-laying animals yet they are grouped under mammals.
Reason : Both of them have seven cervical vertebrae and $12$ pairs of cranial nerves.
