Vedclass · Answer

(B) Assertion $(P)$ is true because most mammals give birth to young ones (viviparous),although there are exceptions like monotremes (e.g.,platypus).Reason $(Q)$ is also true because the presence of external ears or pinnae is a characteristic feature of mammals.However,the fact that mammals are viviparous is not caused by the presence of external pinnae. These are two independent characteristics of the class Mammalia.Therefore,both statements are true,but $P$ is not the correct explanation of $Q$.

Assertion $(P)$: Mammals are viviparous.
Reason $(Q)$: Mammals possess external pinnae.
