If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

Vedclass · Answer

(B) Both the Assertion and the Reason are correct statements.Bats and whales are classified as mammals because they possess mammary glands,have hair (at some stage of development),and are warm-blooded (homeothermic).They also possess a $4$-chambered heart,which is a characteristic feature of mammals.However,the presence of a $4$-chambered heart is not the defining characteristic that classifies an animal as a mammal; rather,it is the presence of mammary glands and other mammalian traits.Therefore,the Reason is a correct statement but does not explain why they are classified as mammals.

Assertion: Bats and whales are classified as mammals.
Reason: Bats and whales have a $4$-chambered heart.
