$S$ and $R$ are both true,but $R$ is not the correct explanation of $S$.

Vedclass · Answer

(B) The statement $S$ is true because $Capelle$ (and other taxonomists) classified organisms like frogs $(Rana)$ and $Ichthyophis$ (a limbless amphibian) under the class $Amphibia$ based on their shared characteristics.The reason $R$ is also true because amphibians,including frogs and $Ichthyophis$,possess a three-chambered heart (two atria and one ventricle).However,the classification of these organisms into $Amphibia$ is based on multiple shared characteristics such as moist skin,lack of scales,and aquatic/terrestrial life cycle,not solely on the presence of a three-chambered heart. Therefore,$R$ is a true statement but not the specific reason for their classification into $Amphibia$.

$S$ - Statement: $Capelle$ classified frogs and $Ichthyophis$ into $Amphibia$.
$R$ - Reason: Frogs and $Ichthyophis$ possess a three-chambered heart.
